United States Army

 
Military History Companion: United States army

In the closing year of the American independence war, Washington wrote his views of a proper military (land forces) policy for the new United States of America. Washington's ‘Sentiments on a Peace Establishment’, completed in May 1783, not only reflected the experiences of the colonial period and the war for independence, but also identified the enduring factors that would shape American armies well into the 20th century. From his experience in two North American wars, Washington did not believe that Americans would ever tolerate the cost or political threat of a large regular army raised and commanded by a strong central government. ‘Altho' a large standing Army in time of Peace hath ever been considered dangerous to the liberties of the Country, yet a few Troops, under certain circumstances, are not only safe, but indispensably necessary. Fortunately for us our relative situation requires but few.’ Washington knew that the state governors and assemblies jealously guarded their control of the militia, the citizen-armies of white male homeowners-voters-taxpayers that had defended their villages and farms since the early 17th century. He also knew that the state forces and his own Continental Army had great difficulty using any sort of conscription system. Such drafts usually meant opening service to ‘the lower sort’ and offering them rewards of land, money, and political rights.

Washington also recognized that militia-based land forces had one military function: the defence of localities and states from direct attack, whether from the sea by Europeans or from Native American warriors, often abetted by Europeans. With a vast new nation to defend, thinly populated away from the Atlantic seaboard, no conceivable national army could protect the western settlers by itself. Even if Congress provided some sort of army to police and protect the national domain, most conspicuously the Northwest Territory beyond the Appalachians and north of the Ohio river, this army would be too small to replace the militia. The difficulty with any militia force was that it included the males who formed the backbone of America's agricultural population, the largest and most important part of its free labour force. Thus, state authorities—let alone a national officer—were unlikely to call out the militia for greater than a 30-60-day period of compulsory service; expeditions that left a state and/or remained in the field for a longer time would have to be raised as volunteers under either national or state authority. These volunteers would insist, like the militia, in selecting their officers (meaning gubernatorial appointment) and establishing their own regulations. They also presented the same problems as the militia in terms of discipline and effectiveness.

Like Washington, the other military experts and political leaders of the post-independence period agreed in principle that (1) the USA still faced threats of internal unrest and foreign invasion and (2) the nation's economic health and political liberties demanded a mixed force of long-service volunteer ‘regulars’ called the US army and state-controlled militia organized for emergency ‘calling forth’ by national and state authorities. Like many other aspects of the American federal system, embodied in the Constitution and the Bill of Rights (Amendments 1-10), the power over the use of military force and the creation of military institutions rested in the hands of many levels of political sovereignty and (in one interpretation of the Second Amendment) in the hands of citizens themselves, who retained the ‘right to bear arms’. This ‘right’ in Great Britain had rapidly disappeared in the face of laws designed to disarm Celtic rebels and disgruntled rural mobs. While the national government had the power to form armies (granted to the Congress in Article 1, Section 8 of the Constitution) and command these armies through the President as C-in-C (Article 2, Section 2), the states bore the principal responsibility for maintaining their own defence forces as they saw fit.

As the land forces developed in the Federalist and Jeffersonian periods (1789-1816), the US army and the militia forces of the states and federal territories exhibited the very strengths and weaknesses that Washington and other nationalists predicted in the 1780s. The US army performed four major functions: expanded the western frontier; manned coastal fortifications with heavy artillery around major harbours or estuaries; developed and produced military ordnance like cannon and muskets; and provided officer-experts in exploration, cartography, and civil engineering, all essential to westward settlement. The territorial and state militias had the duty of mounting an immediate response to invasion, whether by a British army or a Shawnee war party, and of suppressing rebellion, whether it came from slaves, a new immigrant urban working class, or unhappy farmers. Any major conflict, dignified by Congress as a ‘war’, would probably force an expansion of the US army, the formation of volunteer units under national and state authority, and the compulsory call-up of the militia for federal (limited to 90 days a year) or state service. The Militia Act of 1792 expressed this concept, amplified by further legislation in 1808 that promised that the states could share an annual appropriation of $200, 000 for the purchase of muskets if the states could prove they had an organized militia.

The War of 1812 demonstrated the best and worst of the characteristics of America's armies. The regular US army was too small and too dispersed to deter Great Britain; it was too ill-equipped and poorly commanded to either wage offensive operations or even hold its own posts along the Canadian border in 1812. It could, however, expand from 6, 000 to 33, 000 by 1815, and it performed on a few occasions up to European standards against British regulars along the Canadian frontier in 1813 and 1814. Yet the regular army alone could not meet all the military challenges. State governments, usually those most directly threatened, could and did form volunteer units to take the field. Some of these units of infantry, cavalry, mounted infantry, and artillery reached ‘professional’ standards, but they seldom served for longer than six to twelve months. Their effectiveness almost always depended on the charismatic leadership of a local warrior-hero like Andrew Jackson of Tennessee, Richard H. Johnson of Kentucky, or Samuel Smith of Maryland. At one time or another almost 500, 000 citizen-soldiers served in the 1812-15 war, and they contributed to some notable successes like the Creek campaign of 1813 and the defences of Plattsburg, Baltimore, and New Orleans in 1814-15. They also suffered their share of defeats, the sack of Washington (1814) being the most dramatic.

For the rest of the 19th century, American land-force policy endured despite fundamental changes in the conduct of war like the development of breech-loading ordnance and steam-powered transportation as well as the institutional growth in Europe of professionalized officer corps and general staffs. The regular army and the state forces continued to perform their traditional missions with relative effectiveness; their only major failure in maintaining the authority of the national government occurred in 1860-1, and became the American civil war.

The Mexican war had shown how flexible the system might be, especially adaptive to the political realities of a war that divided citizens on party and regional lines. The regiments and batteries of the US army increased in strength through bounty-driven volunteering from 7, 400 to 42, 400; this wartime expansion included the formation of ten brand-new regiments, rich in officer commissions. Nineteen out of 29 state governments provided 61, 000 men in 27 volunteer regiments, enlisted for one year's service or more. The War Department later concluded that 12, 600 militia had also served under involuntary call-up, but these Texas and Louisiana units were probably volunteers in state service and served for very short periods. Some entered federal service to cross state or national boundaries as the Texas Rangers did under Taylor in the army in northern Mexico or the Mormon battalion and New Mexico militia who participated in Gen Alexander W. Doniphan's expedition into north-central Mexico. In retrospect, the regular regiments fought and won the war's major battles, three in Texas and northern Mexico under Taylor in 1846 and six under Scott in the campaign that eventually captured Mexico City. In only one battle (Buena Vista, February 1847) did state volunteers bear the brunt of battle. The regular army also endured the preponderance of combat casualties, 1, 100 of 1, 700 dead and 2, 745 of 4, 102 wounded in action. The war demonstrated—as the War of 1812 had not—that the USA could bring most of its wartime army to bear upon the enemy, even in an overseas expedition.

In terms of land-force policy, the civil war proved little except that mass American armies could kill and maim each other by the hundreds of thousands over a four-year period. Despite some creative myth-making during and after the war about the superior generalship of regular officers (West Point graduates like Lee, Grant, and Sherman) and the staunch service of small contingents of US army ‘regulars’—really wartime enlistees—the war from start to finish was a bloodletting inflicted by citizen-armies upon each other. Of the four million officers and men who served in either the Union or Confederate armies, fewer than 100, 000 had seen service in the regular US army, fought in the war with Mexico as volunteers, or participated in pre-1860 military training as volunteer militia, a category of citizen-soldier that had grown after the 1812-15 war. These units protected or attacked urban ethnic groups, provided ceremonial units in state capitols, satisfied the martial urges of upper middle-class gentlemen, and trained expatriate revolutionaries who wanted to free Ireland, Hungary, and various states in Germany. If one counts every man who had a uniform and took part in military training on a regular basis in 1860 (the US army and the volunteer militia), the total land forces of the USA on the eve of its bloodiest war (both in absolute and population-proportional terms) might have been 56, 000.

A handful of Union army officers, incorporated back into the post-war US army, saw two major lessons in the American civil war: (1) the wartime army like the peacetime army must be run by professional officers, embodied into a general staff and devoted to wartime contingency planning; (2) efficient and timely wartime mobilization required a federal reserve force untainted by state politics that would enlarge the regular US army quickly and provide new units if necessary. After 1871 the German model attracted great interest, but the Swiss system of universal military training also had its attractions. In the meantime, the post-war army went back to its coast defence and frontier forts, numbering only 37, 200 by 1870 and 27, 300 in 1890.

After a decade of war-weariness and sectional strife, the states rebuilt their volunteer state militias (although compulsory service remained a legal option) in the 1870s, in part as a response to racial and labour unrest. In 1890 the volunteer militia, which had largely adopted the title National Guard, may have numbered 100, 000 in units that drilled once a week for a few hours and sometimes went to the field for a week in the summer, both training periods without pay. (States paid Guardsmen only when called to state duty, usually for riot control and disaster relief.) The national government did little to support the Guard other than transfer and sell arms and military equipment under existing federal law.

Some army and Guard officers thought that greater federal subsidies would improve the Guard as a first-line reserve for wartime mobilization, and some states successfully lobbied to have regular officers assigned as Guard advisers and to get federal funds to build armouries. More wartime soldiers, particularly junior officers, might come from the ‘Land Grant’ universities and colleges, established by the Morrill Act of 1862, which required that any state receiving Morrill Act land sales profits had to offer military training for student-volunteers at its new Land Grant university. By the 1890s the students who had received such training might have numbered as many as 100, 000.

Before various military reforms could be established, the USA fought the Spanish-American war, which led to the Philippines insurrection. Waged well beyond the continental USA, the two wars revealed the limitations of the mixed land-force system. Although the War Department wanted to fight Spain with a 64, 000-man all-regular army, supplemented if necessary with federal volunteers, Congress responded to National Guard champions and dictated that state volunteers (under their own officers) be allowed to enter federal service first. The only exceptions were three federal volunteer cavalry regiments, an engineer brigade, some specialist troops, and ten regiments of white and black troops that were supposed to be proof against yellow fever and malaria (‘the Immunes’). The 130 state volunteer regiments (200, 000 officers and men) usually included no more than one-quarter of its soldiers with any sort of prior service, but it was the state governors who commissioned the officers, about 40 for every 1, 000-man regiment. Fewer than half of the state volunteers deployed to the Caribbean or the Philippines; their disease deaths in poorly organized camps in the USA (around 4, 000, compared with fewer than 300 combat deaths) dramatized the fact that the war department had not prepared its support departments and services for wartime expansion.

In the less than twenty years before the USA entered WW I, the military policy of the nation underwent dramatic, but unfinished reform. One factor was the growing appreciation of the impact of new military technology on warfare; in this short period the US army and the National Guard converted to modern magazine rifles, experimented with machine guns, began to use automobiles and trucks, formed aviation units, modernized their artillery, adopted field telephones and primitive radios, and developed motor-powered field engineering. Another development was the awareness that the management of a modern army required extensive pre-war planning and officer education; by 1917 the US army had an officer education system in place to provide European-style commanders and staff officers for large field forces. The greatest challenge was to create a politically legitimate system for raising a wartime army. Just defending the new overseas possessions (Puerto Rico, the Panama Canal Zone, Hawaii, and the Philippines) required far larger regular forces, and the active army reached a peacetime strength of over 100, 000 by 1905, supplemented by Filipino regulars (the Philippine Scouts) and National Guard units in Puerto Rico and Hawaii. To back up this force the War Department and Congress again turned to the National Guard.

In collaboration with the War Department, Congress attempted to reform the National Guard with two major laws, the Militia Acts of 1903 and 1908, and began the ‘nationalization’ of the National Guard as an unlimited federal reserve force, completed by the end of the century. The lever of reform would be federal appropriations for armouries, weapons and equipment, advisers, access to special education and training courses for officers and men, and pay for annual summer field training. The only omitted subsidy was drill pay, and this became a federal responsibility in 1916. The difficulty was some legal uncertainty over whether the federal government could call the National Guard to compulsory service for expeditions abroad for unlimited (‘duration of the emergency’) periods of service. When the War Department examined the issue in 1912, it received an advisory opinion from the US Attorney-General that the federalized National Guard could not be sent abroad unless its members volunteered for such service as individuals. This problem forced the War Department to examine again the feasibility of establishing a federal reserve force, and in 1912 Congress approved a provision that regular enlisted men might volunteer for a reserve corps. The number of soldiers who chose this option would not have formed a company in 1916.

Concerned about the possibility of a war with Mexico after the outbreak of revolution in 1910 and anxious about its security in a world now disordered by WW I, Congress in 1916 passed a National Defence Act. This legislation reflected conflicting sentiments: a generalized interest in ‘preparedness’, the Wilsonian pledge to maintain neutrality yet pressure the Allies and the Central Powers into a compromise peace, and a fear that the USA would soon intervene in the European war. The National Defence Act represented the first peacetime effort to deal with organizing wartime armies and to link those forces to the management of military procurement through a Council of National Defence or ‘war cabinet’ whose authority might extend to economic regulation. The legislation recognized the importance of a ready US army, expanding it to 175, 000 in 111 regiments of infantry, cavalry, and artillery. The National Guard (planned at 400, 000) would become the first source of trained reserve manpower in tactical units, unleashed from potential legal problems by the requirement that any Guardsman receiving federal money would have to take a federal oath that obligated him to overseas service for such a period as the Congress might determine. The mobilization of the Guard for service on the Mexican border proved that Guardsmen would accept this obligation.

Although the Guard lobby and Congress could block any move to create a federal reserve force of units, they conceded that a wartime army would be likely to require the formation of other citizen-soldiers (volunteers and conscripts) into wartime divisions (roughly calculated at around 20, 000 officers and men) and much-enlarged army service and support units. The National Defence Act of 1916 focused on identifying and training officers in peacetime for wartime service either as combat leaders or staff specialists; the legislation created an Officer Reserve Corps (subdivided by combat arms and staff departments) that would come from graduates of university-based university cadet programmes, the summer training camps organized and run by the army since 1912, and from already-licensed professionals like doctors, lawyers, dentists, and engineers. Another unstated assumption was that the War Department would for the first time create officer-training courses in wartime that would supply combat arms leaders to the expanded army. This concept, which assumed the possibility of forming an army of two million, did not reflect any plan to intervene in the European war, but the possibility of a later war with Japan or some future European enemy.

American entry in WW I in April 1917 tested every aspect of the nation's land-forces policy and found it barely satisfactory. Upon entry into the war, the Wilson administration and Congress accepted with great reluctance the reality that the war would be won or lost on the western front. To influence that outcome the USA would have to form a massive American Expeditionary Force (AEF), which eventually numbered over two million. The only way to conserve on shipping and speed up the American reinforcement was to arm the AEF with French and British weapons and equipment. Such adjustments cut almost a year (from both German and American estimates) from the time required to form an American army in France. In the crisis the US government turned to wartime conscription and Congress passed a ‘Selective Service’ Act in May 1918. This law first stirred volunteering for the regular US army and federalized National Guard in 1917 and later in the same year provided a foundation for the creation of a ‘National Army’ of draftees. The legitimacy of the system rested in the decentralization and civilization of the induction process; the locus of deciding who served and who received exemptions and deferments rested in 4, 648 local boards staffed by civilians, not the despised military officers used by the Union and Confederacy in the civil war. Voluntary enrolment for the draft produced more than 24 million names and fewer than 1 million avoiders. By war's end two-thirds of America's soldiers (2.8 million) had entered the army through the draft.

The performance of the AEF left a set of ambiguous lessons for the post-war review of land-force policy. The AEF had found plenty of brave junior officers and enlisted men in its ranks; both regulars and temporary officers (Guardsmen, reserves, and graduates of the officer-candidate schools) had performed with unexpected expertise, a credit to their own intelligence and the AEF school system. Most of the AEF's problems on the battlefield stemmed from poor staff work, primitive transportation logistics, and the inadequate use of supporting arms. No doubt some of these problems might have been eased had the AEF not existed but had been treated like British Commonwealth and French colonial divisions; that is, amalgamated into a larger national army. Such a solution was not congruent with Wilson's diplomacy nor Pershing's national and institutional pride. The AEF, which suffered most of its 55, 000 dead in a span of only fifteen weeks in 1918, had struggled until the war's last week. If less traumatized than their civil-war forebears, army officers returned from France full of ideas on how to modernize and organize American land forces.

Land-force policy and army politics felt the impact of new forms of warfare: the employment of military aircraft of various types for a wide range of missions. The Air Service AEF, an organizational stepchild of the Signal Corps, performed almost every modern airwar mission except strategic bombardment. Army aviators, flying French and British aircraft, protected their own forces, raided German airbases and installations, bombed transportation systems, took photographs, spotted artillery targets, carried messages, and strafed and bombed front-line positions. At the war's end the Air Service numbered 200, 000 officers and men, one-quarter of them in Europe. One group of army aviators, rallying around the charismatic AEF air combat leader Mitchell, argued that the army's aviation force should be an independent service with strategic bombing its primary mission; other air and ground officers believed that army aviation should be integrated with the ground forces in order to insure rapid, decisive battlefield victory. Although they did not use the term ‘air-land battle’, that is exactly what these moderate reformers envisioned. After 1918 any attempt at military reform invariably had to cope with the contentious issue of the future of army aviation.

Reflecting its understanding of the lessons of WW I, Congress passed the National Defence Act of 1920 on the assumption that the mixed armies it created in 1916 and 1917 needed little change. The regular army and National Guard still would provide infantry-artillery divisions (each about 25, 000 soldiers in 1920) while the Officers Reserve Corps would train peacetime officers for an expanded wartime army. One new concept in the 1920 Act was the creation of army Reserve divisions manned in only cadre status (1, 000 or fewer officers and NCOs) ; these federal reservists would prepare for their wartime role of training divisions of draftees for combat. The continental USA was divided into nine corps areas whose commanding generals would train one US army division, two National Guard Divisions, and three army Reserve cadre divisions. All of the divisions would be organized and equipped the same (at least on paper), which allowed National Guard divisions to form tank companies and aviation squadrons, the latter units eventually becoming the Air National Guard in 1947. The Congress intended that the regular army and the National Guard would number about 715, 000 officers and men in peacetime while all elements of the new ‘Army of the United States’ would be used as the foundation for a wartime army of 5-7 million. Congressional economizing, deepened by the economic depression of the 1930s, reduced the actual strength of both armies by 1939 to only 380, 000.

The failure to man and train the Army of the United States (AUS) in the 1930s reflected two major problems. The first was the lack of equipment modernization, which the war department and combat arms commanders recognized; equipment shortages (and the growing obsolescence of the WW I weapons) meant that much of the army could not be combat-ready for at least two years. One option was to limit investment in new weapons like tanks; another was to develop prototypes of new weapons (like the 105 mm howitzer and the M-1 semi-automatic rifle) but not field them. The army pursued better mobility, especially for its service and supply units, through comprehensive motorization, but the willy-nilly purchase of trucks and cars made automotive maintenance difficult and costly, which made Congress unhappy.

The other problem was the new popularity of the Army Air Corps, established as an equal arm in 1920 and then as a super-arm with special allowances to develop aircraft, train pilots, build airbases, and manage its own affairs, all assured in the Air Corps Act of 1926. The Air Corps may have dominated one-quarter of all army spending in the 1930s, and it enjoyed close and co-operative relations with American commercial aviation. In 1931 the army and navy agreed that the Air Corps had an important role in coast defence, which justified the highest priority development of the XB-17, a long-range bomber. In 1935 the emerging bomber force had its squadrons unified under the commanding general, GHQ Air Force. This change meant that much of the Air Corps no longer supported the ground army (the armies and corps), but prepared to wage war by strategic bombardment, smashing the will and industrial might of any future enemy by direct attack on his cities and economic assets.

Concerned with the lack of readiness of all elements of the AUS, Gen Malin Craig, the COS, decided to focus his scarce resources on portions of the US army and the National Guard; after 1935 the army would train and equip a 400, 000-man field army named the Initial Protective Force. Equipment shortages restricted the training of this grouping of ‘minuteman’ divisions; Craig estimated that he needed an additional $4 billion to arm and equip the force. This sum was eight times the army's entire budget in 1935.

The Japanese invasion of China in 1937 and the Nazi-Soviet conquest of Poland in 1939 did not change the army except to accelerate some procurement and modernization plans. When the War Department tried to put its plan for more urgent procurement into effect, the Industrial Mobilisation Plan, the Congress rejected the plea for army modernization. The fall of France in 1940 created a new sense of crisis, and the Congress approved the federalization of the National Guard and the enactment of a new Selective Service Act to draft men for peacetime military training. The fundamental concern was to deter Japan from using German successes to seize the European colonial empires in South-east Asia and the Philippines.

The War Department general staff drafted the ‘Victory Program’ of 1941, a blueprint for the creation of a wartime army of 8.8 million officers and men, a force (as planned) that would produce a ground force of 213 divisions, about half of them mechanized or motorized, and an air force of 195 groups, half of them bombers. In the same summer the Air Corps became the Army Air Forces (USAAF), whose operational forces would be assigned to a theatre commander, not a ground forces general. The Commanding General, USAAF, would be the DCOS of the army, answerable only to the COS, US army. Two years later the army's authoritative doctrinal manual on the conduct of operations stated that army aviation had a co-equal role with the ground forces in winning wars. The USAAF planners in 1941 also drafted their version of an air campaign against Germany; this war of strategic bombardment would ensure air superiority and crush the industry that supplied the Axis ground forces. None of these hopes would materialize completely or in quite the way the planners imagined, but the plans represented a dramatic shift away from massing resources in a large ground army to focusing on an élite, technologically advanced, and capital-intensive air force in order to spare lives in conventional ground battles.

The AUS met its greatest test in the two-front struggle with the Axis in WW II. The AUS split into three functional groupings: Army Ground Forces, Army Air Forces (USAAF), and Army Service Forces (ASF). In terms of numbers and training quality of personnel, the Army Ground Forces took second place to the USAAF Air Forces and ASF; of the 11 million soldiers who served in WW II, only one-third served in the ground forces, principally the 89 divisions formed and deployed abroad. The USAAF absorbed 2.5 million army airmen, and the ASF, faced with global transportation and base-building challenges, grew to three million officers and men. Early in the war army COS George Marshall pledged that the army would produce the best soldiers, armed with the best weapons, in the world. This goal proved to be beyond the army's means. The massive investment of money and quality manpower in the USAAF remains controversial, but it is hard to imagine the army fighting the Wehrmacht in Europe without the benefits of its strategic bombing campaign and the direct support of tactical aviation. In quantitative terms the army directed two-thirds of its combat power against Germany and Italy and one-third against Japan.

The demobilization after WW II and the subsequent development of Cold War military challenges posed by the USSR in central Europe brought more changes to the army. First, it lost almost all its pilots and aircraft (and the guarantee of close air support) to the US Air Force (USAF) in the National Security Act of 1947. By 1949 its principal civilian official, the Secretary of War, had become the Secretary of the Army, subordinated to the Secretary of Defence and stripped of cabinet membership. The army COS became a member of the Joint Chiefs of Staff, eventually (1986) subordinated to a powerful Chairman invested with special access to the Secretary of Defence and the President. Fundamentally organized and equipped for a mechanized war with the USSR as part of the NATO collective defence alliance, the army, nevertheless, fought two extended ground wars in Asia, neither of which brought it much public acclaim. Instead the wars in Korea and Vietnam used up lives, morale, money for continued modernization, and a good deal of the public sympathy given the army in WW II. The most positive benefit of the two wars was the re-emergence of army aviation as a helicopter force for airmobile warfare.

The Cold War army retained much of its WW II organizational character with an active force that varied between 500, 000 and 1.6 million officers and men formed into between ten and twenty divisions, reinforced with corps troops and separate brigades. The army Reserve and the army National Guard shared the role of providing deployable units with the Reserve stressing service and support units and the Guard combat units, most of which shrank from divisions to brigades by the 1990s. Both reserve components provided units and individuals for the expanded wartime armies of the Korean and Vietnam eras, although the compulsory mobilization of the Vietnam war did not occur until 1968, too late to influence the course of the war. The Korean war mobilization, on the other hand, rebuilt a strategic reserve in the USA, provided veterans for combat service in Korea, in Germany in 1951-2, and allowed the creation of the Seventh Army. The Gulf war also required the army to mobilize Reserves and Guardsmen to strengthen the US Third Army, principally with artillery and support units. Of the 381, 000 soldiers who fought Iraq, 134, 300 male and female soldiers came to the war from federalized reserve units. The subsequent reduction of the active army in the 1990s had one happy benefit, the release of experienced soldiers to reserve units and the equipping of these units with first-line weapons and equipment.

The army also grappled with several manning changes that changed its character. None of the changes came without organizational stress. One fact of life was that the Cold War ground forces could not be manned in sufficient strength without peacetime conscription, enacted in 1948 and continued until 1973. This army of true volunteers, coerced volunteers, and conscripts meant a high turnover, heavy training load, and an irreducible minority of ‘summer soldiers’. The army also tried to balance its emphasis on ready forces, especially in Germany and Korea, with the maintenance of a vast training establishment designed for wartime expansion. By its own admission it retained too many bases, stored too much equipment, supported officer commissioning programmes that could not be justified on cost grounds, and created an active duty officer corps that lacked cohesion and common values. Many army ‘warriors’ sought refuge in élite units: rangers, special forces, attack helicopter squadrons, parts of the armoured forces, and technically advanced artillery and air defence units. The creation of an all-volunteer force in the 1980s and 1990s helped build ‘one army’ in the functional sense, but other factors brought stress from other directions.

One way the army had always justified its existence was to argue that it served as an employer of the American underclass and an agency of assimilation for immigrants, dispossessed farmers, and unemployed, unskilled workers. After WW II this social function, which was real if difficult, received a stern test. First, conscription and (later) the high wages of the volunteer army brought young men into the army with few skills, unfinished education, and no taste for authority and discipline. The drug use of the 1960s and 1970s (pandemic in the army) reflected a rootless youth culture that made training difficult.

This problem was further exacerbated by a presidential decision (long overdue) in 1948 to give African-American soldiers wider opportunities as officers and senior enlisted men, including the command of whites, and to provide meaningful training to black enlistees to the best of their abilities, not just assign them to segregated units with minimal combat and logistical missions. This policy paid real dividends until the 1970s when unemployed black youths flooded the army and went into direct battle with their officers and NCOs and their white comrades. Only by reducing the army and applying higher enlistment standards to all recruits could racial violence be reduced, essential in an army that is now one-third black. Just as this problem subsided, the army found itself accepting the fact that almost 12 per cent of its force would be female, a trend started in 1948. It accelerated in the 1970s when male recruits came in short supply and the Congress accepted the argument that ‘equal opportunity’ had gender as well as racial meaning. The American army of men, women, soldiers of many races and ethnic origins, and even soldiers with unconventional sexual tastes, is a wonder of the world at the end of the 20th century. Optimists believe it will eventually produce the élite androgynous ‘starship troopers’ of the future, adept with wizard weapons and full of traditional warrior virtues detached from old notions of masculinity. Pessimists believe that the army will mirror the experience of the Roman legions, weakened by too-long service abroad, divided by nationalities and deviant subcultures, and devoted to its own comfort and perpetuation, not defence. The past of the American army suggests that it will endure, but that the process will be difficult and test the devotion of those men and women who will try to sustain its honour.

Major branch of the U.S. military forces, charged with preserving peace and security and defending the nation. The first regular U.S. fighting force, the Continental Army, was organized by the Continental Congress on June 14, 1775, to supplement local militias in the American Revolution. It was placed under the control of a five-member civilian board, and U.S. military forces have remained in civilian control ever since. The U.S. Constitution named the president as commander in chief, and in 1789 the civilian Department of War was established to administer the armed forces. The Continental Army was officially disbanded in 1783, and a small regular army was established. Thereafter, the army's size increased during times of crisis, swelled by conscription, and decreased during peacetime. The Department of the Army is organized as a military section of the Department of Defense and is headed by the Secretary of the Army. The Army Staff gives advice and assistance to the secretary and administers civil functions, including the civil-works program of the Corps of Engineers. The army also administers the U.S. Military Academy at West Point. In 2000 there were about 400,000 soldiers on active duty.

Army, United States, came into being on 14 June 1775 by an act of the Second Continental Congress. The new Continental army sustained the patriot cause in the American Revolution and established several important traditions, including subordination of the army to the civilian government, reliance on citizen-soldiers (militia, volunteers, draftees, and organized reserves) to bolster the regular army in wartime, and a quick return to a small core of professional soldiers during peacetime. The pattern of American war—a sudden and massive buildup of army manpower and material after years of neglect, quickly followed by an equally rapid and sweeping demobilization with the outbreak of peace—persisted for the next 175 years. Breaking with tradition, the U.S. Army after 1945 remained large and in a high state of readiness even in peacetime due to the Cold War. Even with the disintegration of the Communist bloc in 1989 and the collapse of the Soviet Union, the U.S. Army has remained the preeminent army in the world.

Missions

Historically the U.S. Army has performed a variety of missions, among them homeland defense, expeditionary military efforts, scientific and humanitarian duties, and the restoration of domestic order.

The army's most fundamental mission is to safeguard the lives, property, and territorial rights of the United States and its citizens. The army was called to homeland defense against the forces of Great Britain in the American Revolutionary War (1775–1783) and the War of 1812 (1812–1815). One might also include in this category the American Civil War (1861–1865), although the federal government led by President Abraham Lincoln never recognized the southern Confederacy as a sovereign state. However, it took nearly four years of bloody conflict before the federal Army of the Union subdued the rebellious eleven southern states and restored, in fact as well as in law, the political integrity of the nation. Following the Civil War, the increasingly close relationship between the United States and its two neighbors, Canada and Mexico, gave the nation a high degree of continental security, although the army continued to man dozens of coastal installations. The army also served a constabulary role on the expanding frontier, which frequently brought it into conflict with Native Americans.

U.S. foreign policy, especially since the late-nineteenth century, has often required the army to fulfill international missions. Expeditionary armies fought in major declared wars such as the Spanish-American War (1898), World War I (1917–1918), and World War II (1941–1945), as well as large-scale but undeclared wars including the Korean War (1950–1953), Vietnam War (1957–1975), and Persian Gulf War of 1991 (1991). The army has intervened to rescue American citizens (such as the Boxer Rebellion in China in 1900) and mounted campaigns to retaliate for the loss of American lives and property, including the Punitive Expedition Into Mexico in 1916–1917, an unsuccessful attempt to capture the bandit Francisco (Pancho) Villa. In the twentieth century, the army has fought counterinsurgency wars (such as in the Philippines in 1898–1899, Central America and the Caribbean between the 1910s and 1930s, and Southeast Asia in the early 1960s) and acted as a peacekeeping force in dysfunctional societies (such as Haiti in 1994 and Bosnia in 1995).

The army has promoted scientific discovery and national development. The U.S. Army academy at West Point, founded in 1802, has helped train generations of engineers and scientists. When the United States acquired the Louisiana Purchase, it was an army expedition led by two officers, Captain Meriwether Lewis and Lieutenant William Clark, which first explored the territory in an epic three-year journey (1804–1806). As the nation expanded from east to west over the next several decades, army engineers surveyed for roads, canals, and railroads and constructed bridges, public buildings, telegraph lines, and aqueducts. The most famous and complex engineering project the army oversaw was the Panama Canal, completed in 1914. Between the 1880s and 1918, the army also helped survey and administer the emerging system of national parks to promote conservation and recreation. During the Great Depression in the 1930s, the army played a central role in developing the Civilian Conservation Corps, a New Deal program to give men work on conservation projects. In the Cold War era, the army contributed to the space program and researched new materials and technology that also had consumer applications.

In times of great civil disorder, the army sometimes helped civilian agencies restore public authority and safety. It dispersed the Whiskey Rebellion of 1794 in western Pennsylvania when angry farmers rebelled against excise taxes on liquor and stills, attempted to stop a guerrilla war between pro-and antislavery forces that began in Kansas in 1854, and mobilized to stop the violence and destruction of property during the great Railroad Strike of 1877. Between 1863 and 1877, the army also acted as an administrator and constabulary force in the South during Reconstruction, supervising the reintegration of the confederate states into the union, distributing aid to former slaves through the Freedmen's Bureau, and enforcing (albeit with limited effect) the new rights of black citizens. Nearly a century later, when the federal government enforced the racial integration of Central High School in Little Rock, Arkansas, in 1957, paratroopers helped enact the law. In times of dire emergency, the army has contributed manpower, expertise, and equipment to cope with natural disasters such as tornadoes, floods, forest fires, and earthquakes as well as man-made disasters such as riots and terrorist attacks.

Organization

The organization of the army has changed dramatically since 1775, influenced by tactical innovations, technological improvements, and financial and political debates within the government.

During the American Revolution, the basic tactical unit was the brigade, composed of several regiments each recruited from a specific colony. Each brigade of between 1,000 and 2,500 men was either named for its commander or given a numerical designation. Most Continental soldiers were infantry, supported by a smaller number of artillery and cavalry units. Commanders relied on a few personal aides to carry out staff work, and many officers were chosen on the basis of their social standing, political connections, or financial resources. The support elements, such as quartermaster and medical details, were typically formed on an ad hoc basis with civilian laborers.

Immediately following the Revolutionary War, the army shrank to a mere 718 men because Congress saw a large standing army as inimical to democracy and ruinously expensive. However, the continued threat from hostile Indians and European powers with territorial ambitions in North America convinced Congress to gradually expand the army, while the new Constitution passed in 1789gave the federal government more power to legislate and tax on behalf of national defense. In the years between 1792 and 1796, the army expanded to more than 5,000 men organized into a single legion, a mixed tactical formation with infantry, artillery, and cavalry. The legion proved to be unwieldy, however, and in 1796 the army adopted the regiment as its basic tactical formation, a system of organization that would persist until the twentieth century.

During the War of 1812 against Great Britain, volunteers and federalized militia supplemented regulars to form ad hoc field armies, often with minimal logistical support and widely divergent standards of discipline and drill. Although Congress authorized the army to grow to 35,000 men, with an additional 50,000 volunteers and 100,000 militia, the actual size of field armies was rarely more than several thousand during any campaign.

In the years between 1815 and 1846, the army retained an average strength of little more than 6,000 men, mostly occupied with Indian wars and garrison duty. With the outbreak of war against Mexico in 1846, Congress called for 50,000 volunteers rather than expand the regular army. Through the next two years of conflict, the expeditionary armies in Mexico—the largest was just 12,000 men—were a mixture of well-trained regulars and eager but unruly volunteers.

America's next conflict, the Civil War, exceeded all previous wars in size and intensity. The federal army, only 16,000 at the outbreak of war in April 1861, expanded with a massive stream of new soldiers—volunteers, mostly—and eventually surpassed one million men on active duty in May 1865. The Union organized field armies as large as 100,000 men, and most regiments were made up of soldiers from a particular state or region, often with a distinctive ethnic or racial identity (including the first African-American combat regiments).

The army shrank again quickly after the Civil War, falling to 54,302 in 1866 and then just 27,442 by 1876. When war broke out with Spain in April 1898, Congress authorized a call for 200,000 volunteers, only some of which joined the regulars to see action in Cuba (although more of the volunteers saw action against guerrillas in the Philippines).

The Spanish-American War revealed serious tactical and logistical shortcomings in the army that Secretary of War Elihu Root pledged to reform in 1903. Under his guidance, the army created a general staff—a permanent headquarters of senior-level officers—to develop doctrine and to plan for future conflicts. Although the army made great strides in training and organization over the next decade, it was still far too small for the task when the United States entered World War I in April 1917.

The wartime army drew upon three sources—an expanded regular army, the federalized National Guard, and the draftees of the National Army—to eventually reach a total of 1.3 million men. Forces were organized around a large, "square" division (28,000 men divided into two brigades with two regiments each) to compensate for the lack of officers, to maximize firepower, and to build a unit that could handle sustained combat. The army grew to sixty-four divisions during World War I, forty-three of which deployed to Europe. Airplane and tank units were added during the war, new technologies that would revolutionize the battlefield in the twentieth century.

At the conclusion of the war troop strength declined once again, and by 1922 its size was only 144,000 officers and men. The isolationist and fiscally conservative policies of the 1920s and 1930s kept the army small, but the totalitarian menace of Germany, Japan, and Italy led to its expansion once again with the Selective Training and Service Act of 1940. When the United States entered the war in December 1941, there were already 1.6 million men in the army, organized around "triangular" divisions averaging 12,000 men that offered better mobility and command efficiency than the "square" divisions of World War I. In 1943, the air services became a semi-independent branch called the U.S. Army Air Forces. During the war, the army fielded eighty-nine divisions (one light, one cavalry, five airborne, sixteen armored, and sixty-six infantry) within a total strength of 7.7 million personnel. Sixty-eight divisions fought in the European theater and twenty-one in the Pacific.

Although the army shed much of its strength following Japan's surrender in September 1945, the emergence of the Cold War halted and then reversed the decline. The number of active divisions fell from eighty-nine in 1945 to just twelve in 1947—the Air Force also became a fully independent service branch on 18 September of that year—but rising tensions with the communist world and the outbreak of the Korean War in June 1950 spurred a major rebuilding effort. The army committed eight combat divisions and formally abolished racial segregation in its units during the war. By 1953 it had grown to 1.5 million men, and even when the war ended Congress retained a force of one million on active duty.

Between 1956 and 1960, the army experimented with a "pentomic" division structure based on five battle groups designed to operate on an atomic battlefield. The formation proved unsuitable and a new, more flexible division structure was adopted in 1961. The so-called ROAD division was organized around brigade task forces adaptable to a wide range of missions, ranging from atomic to unconventional warfare.

Between 1961 and 1972, the army fought a major conflict in South Vietnam that required at its peak the equivalent of nine combat divisions and nearly 361,000 men (out of a total strength of 1.5 million), and developed a new kind of "airmobile" division based around helicopters for greater mobility. A drawdown after the war reduced manpower to 650,000 men, and the end of the draft in 1973 transformed the army into an all-volunteer force. Changing social mores and more opportunities in the army led to a growing number of women to join.

After a period of turmoil following Vietnam, the army began to rebuild in the 1980s as tensions rose again with the Soviets. When the Warsaw Pact collapsed in 1989, the army devoted more attention to the unstable Middle East region. Following Iraq's invasion and occupation of Kuwait in August 1990, the army committed the equivalent of seven divisions and nearly 300,000 soldiers. The Persian Gulf War culminated with the retaking of Kuwait in February 1991, accomplished in fewer than 100 hours of ground combat. In the decade after the war, the army evolved into a smaller, leaner organization—471,000 personnel in 2001—but continued to fulfill a wide variety of global missions, including peacekeeping efforts, special operations training, and preparations for conventional war.

Following the terrorist attacks against the World Trade Center in New York City and the Pentagon in Washington, D.C., on 11 September 2001, the army began preparing for war against the Al Qaeda terrorist network and its state sponsors. Between October and December 2001, Army Special Forces soldiers played a key role in defeating the Taliban regime of Afghanistan, the primary state sponsor of Osama bin Laden's Al Qaeda network, by directing air strikes against the enemy and by helping to organize friendly Afghan troops. When Army conventional forces, particularly from the 101st Airborne and Tenth Mountain Divisions, began operating in Afghanistan, they enjoyed considerable success in damaging and disrupting the Al Qaeda network, an effort that continues and will likely last for many years.

The United States Army is the branch of the United States Military responsible for land-based military operations. It is the largest and oldest established branch of the U.S. military and is one of seven uniformed services. The modern Army has its roots in the Continental Army which was formed on 14 June 1775,[1] before the establishment of the United States, to meet the demands of the American Revolutionary War. Congress created the United States Army on 14 June 1784 after the end of the war to replace the disbanded Continental Army. The Army considers itself to be descended from the Continental Army and thus dates its inception from the origins of that force.[1]

The primary mission of the Army is to "provide necessary forces and capabilities ... in support of the National Security and Defense Strategies."[2] Control and operation is administered by the Department of the Army, one of the three military departments of the Department of Defense. The civilian head is the Secretary of the Army and the highest ranking military officer in the department is the Chief of Staff, unless the Chairman of the Joint Chiefs of Staff or Vice Chairman of the Joint Chiefs of Staff are Army officers. The Regular Army reported a strength of 539,675 soldiers; the Army National Guard (ARNG) reported 360,351 and the United States Army Reserve (USAR) reported 197,024 putting the combined component strength total 1,097,050 soldiers (2008 Financial Year).[3]

History

Origins

Storming of Redoubt #10 during the Siege of Yorktown.

The Continental Army was created on 14 June 1775 by the Continental Congress as a unified army for the states to fight Great Britain, with George Washington appointed as its commander.[1] The Army was initially led by men who had served in the British Army or colonial militias and who brought much of British military heritage with them. As the Revolutionary war progressed, French aid, resources, and military thinking influenced the new army, while Prussian assistance and instructors, such as Friedrich Wilhelm von Steuben, had a strong influence.

George Washington used the Fabian strategy and used hit-and-run tactics, hitting where the enemy was weakest, to wear down the British forces and their Hessian mercenary allies. Washington led victories against the British at Trenton and Princeton, and then turned south. With a decisive victory at Yorktown, and the help of the French, the Spanish and the Dutch, the Continental Army prevailed against the British, and with the Treaty of Paris, the independence of the United States was acknowledged.

After the war, though, the Continental Army was quickly disbanded as part of the American distrust of standing armies, and irregular state militias became the new nation's sole ground army, with the exception of a regiment to guard the Western Frontier and one battery of artillery guarding West Point's arsenal. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army. The first of these, the Legion of the United States, was established in 1791.

19th century

The War of 1812 (1812–1815), the second and last American war against the British, was less successful than the Revolution had been. An invasion of Canada failed, and U.S. troops were unable to stop the British from burning the new capital of Washington, D.C.. However, the Regular Army, under Generals Winfield Scott and Jacob Brown, proved they were professional and capable of defeating a British army in the Niagara campaign of 1814. Two weeks after a treaty was signed, though, Andrew Jackson defeated the British invasion of New Orleans. However this had little effect, as per the treaty both sides returned to the status quo.

Between 1815 and 1860, a spirit of Manifest Destiny was common in the U.S., and as settlers moved west the U.S. Army engaged in a long series of skirmishes and battles with Native Americans that the colonists uprooted. The U.S. Army also fought the short Mexican–American War, which was a victory for the United States and resulted in territory which became all or parts of the states of California, Nevada, Utah, Colorado, Arizona, Wyoming and New Mexico.

The Battle of Gettysburg, the turning point of the American Civil War

The Civil War (1861–1865) was the most costly war for the U.S.[citation needed] After most states in the South seceded to form the Confederate States of America, CSA troops opened fire on the Union-held Fort Sumter in Charleston, South Carolina, starting the war. For the first two years Confederate forces solidly defeated the U.S. Army, but after the decisive battles of Gettysburg in the east and Vicksburg in the west, combined with superior industrial might and numbers, Union troops fought a brutal campaign through Confederate territory and the war ended with a Confederate surrender at Appomatox Courthouse in April 1865. Based on 1860 census figures, 8% of all white males aged 13 to 43 died in the war, including 6% in the North and 18% in the South.[5]

Following the Civil War, the U.S. Army fought a long battle with Native Americans, who resisted U.S. expansion into the center of the continent. But by the 1890s the U.S. saw itself as a potential international player. U.S. victories in the Spanish-American War (1898) and the controversial and less well known Philippine-American War (1898–1913), as well as U.S. intervention in Latin America and the Boxer Rebellion, gained America more land.

In 1910 US Signals Corps acquired and flew US Army's first aircraft, the Wright Type A biplane.[6] The United States joined World War I (1914–1918) in 1917 on the side of Russia, Britain and France. U.S. troops were sent to the front and were involved in the push that finally broke through the German lines. With the armistice on 11 November 1918, the Army once again decreased its forces.

The U.S. joined World War II after the Japanese attack on Pearl Harbor on 7 December 1941. On the European front, U.S. Army troops formed a significant portion of the forces that captured North Africa and Sicily. On D-Day and in the subsequent liberation of Europe and defeat of Germany, millions of U.S. Army troops played a central role. In the Pacific, Army soldiers participated alongside U.S. Marines in the "island hopping" campaign that wrested the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, Army troops were deployed to Japan and Germany to occupy the two defeated nations. Two years after World War II, the Army Air Forces separated from the Army to become the United States Air Force on 18 September 1947 after decades of attempting to separate. Also, in 1948 the Army was desegregated.

However, the end of World War II set the stage for the East-West confrontation known as the Cold War (late 1940s to early 1990s). With the outbreak of the Korean War, concerns over the defense of Western Europe rose. Two corps, V and VII, were reactivated under Seventh United States Army in 1950 and American strength in Europe rose from one division to four. Hundreds of thousands of U.S. troops remained stationed in West Germany, with others in Belgium, the Netherlands and the United Kingdom, until the 1990s in anticipation of a possible Soviet attack.

During the Cold War, American troops and their allies fought Communist forces in Korea and Vietnam (see Domino Theory). The Korean War began in 1950, when the Soviets walked out of a U. N. Security meeting, removing their possible veto. Under a United Nations umbrella, hundreds of thousands of U.S. troops fought to prevent the takeover of South Korea by North Korea, and later, to invade the northern nation. After repeated advances and retreats by both sides, and the Peoples' Republic of China 's entry into the war, a cease-fire returned the peninsula to the status quo in 1953.

The Vietnam War is often regarded as a low point in the Army's record due to the use of drafted personnel, the unpopularity of the war with the American public, and frustrating restrictions placed on the Army by US political leaders (i.e. no invading communist held North Vietnam). While American forces had been stationed in the Republic of Vietnam since 1959, in intelligence & advising/training roles, they did not deploy in large numbers until 1965, after the Gulf of Tonkin Incident. American forces effectively established and maintained control of the "traditional" battlefield, however they struggled to counter the guerrilla hit and run tactics of the communist Viet Cong and the North Vietnamese Army. On a tactical level, American soldiers (and the US military as a whole) never lost a sizable battle.[citation needed] For instance in the Tet Offensive in 1968, the US Army turned a large scale attack by communist forces into a massive defeat of the Viet Cong on the battlefield (though at the time the offensive sapped the political will of the American public) which permanently weakened the guerrilla force; thereafter, most large scale engagements were fought with the regular North Vietnamese Army. In 1973 domestic political opposition to the war finally forced a US withdrawal. In 1975, Vietnam was unified under a communist government.

The Total Force Policy was adopted by Chief of Staff of the Army General Creighton Abrams in the aftermath of the Vietnam War and involves treating the three components of the Army – the Regular Army, the Army National Guard and the Army Reserve as a single force.[7] Believing that no US president should be able to take the United States (and more specifically the US Army) to war without the support of the American people, General Abrams intertwined the structure of the three components of the Army in such a way as to make extended operations impossible, without the involvement of both the Army National Guard and the Army Reserve.

The 1980s was mostly a decade of reorganization. The Army converted to an all-volunteer force with greater emphasis on training and technology. The Goldwater-Nichols Act of 1986 created Unified Combatant Commands bringing the Army together with the other four military under unified, geographically organized command structures. The Army also played a role in the invasions of Grenada in 1983 (Operation Urgent Fury) and Panama in 1989 (Operation Just Cause).

By 1989 Germany was nearing reunification and the Cold War was coming to a close. The Army leadership reacted by starting to plan for a reduction in strength. By November 1989 Pentagon briefers were laying out plans for 'Operation Quicksilver,' a plan to reduce Army endstrength by 23%, from 750,000 to 580,000.[8] A number of incentives such as early retirement were used. In 1990 Iraq invaded its smaller neighbor, Kuwait, and U.S. land forces, led by the 82nd Airborne Division, quickly deployed to assure the protection of Saudi Arabia. In January 1991 Operation Desert Storm commenced, a U.S.-led coalition which deployed over 500,000 troops, the bulk of them from U.S. Army formations, to drive out Iraqi forces. The campaign ended in total victory for the Army, as Western coalition forces routed the Iraqi Army, organized along Soviet lines, in just one hundred hours.

After Desert Storm, the Army did not see major combat operations for the remainder of the 1990s. Army units did participate in a number of peacekeeping activities, such as the UN peacekeeping mission in Somalia in 1993, where the abortive Operation Gothic Serpent led to the deaths of eighteen American soldiers and the withdrawal of international forces. The Army also contributed troops to a NATO peacekeeping force in the former Yugoslavia in the middle of the decade.

21st century

After the September 11 attacks, and as part of the Global War on Terror, U.S. and NATO combined arms (i.e. Army, Navy, Air Force, Marine, Special Operations) forces invaded Afghanistan in 2001, replacing the Taliban government.

The Army took part in the combined U.S. and allied invasion of Iraq in 2003. In the following years the mission changed from conflict between regular militaries to counterinsurgency, with large numbers of suicide attacks resulting in the deaths of more than 4,000 U.S. service members (as of March 2008) and injuries to thousands more.[9] The lack of stability in the theater of operations has led to longer deployments for Regular Army as well as Reserve and Guard troops.

The task of organizing the U.S. Army commenced in 1775.[11] During World War I, the "National Army" was organized to fight the conflict.[12] It was demobilized at the end of World War I, and was replaced by the Regular Army, the Organized Reserve Corps, and the State Militias. In the 1920s and 1930s, the "career" soldiers were known as the "Regular Army" with the "Enlisted Reserve Corps" and "Officer Reserve Corps" augmented to fill vacancies when needed.[13]

In 1941, the "Army of the United States" was founded to fight World War II. The Regular Army, Army of the United States, the National Guard, and Officer/Enlisted Reserve Corps (ORC and ERC) existed simultaneously. After World War II, the ORC and ERC were combined into the United States Army Reserve. The Army of the United States was re-established for the Korean War and Vietnam War and was demobilized upon the suspension of the Draft.[13]

Currently, the Army is divided into the Regular Army, the Army Reserve, and the Army National Guard.[12] The Army is also divided into major branches such as Air Defense Artillery, Infantry, Aviation, Signal Corps, Corps of Engineers, and Armor. Prior to 1903 members of the National Guard were considered state soldiers unless federalized by the President. Since the Militia Act of 1903 all National Guard soldiers have held dual status: as National Guardsmen under the authority of the governor of their state and as a reserve of the U.S. Army under the authority of the President.

Since the adoption of the total force policy, in the aftermath of the Vietnam War, reserve component soldiers have taken a more active role in U.S. military operations. Reserve and Guard units took part in the Gulf War, peacekeeping in Kosovo, and the 2003 invasion of Iraq.

Various State Defense Forces also exist, sometimes known as State Militias, which are sponsored by individual state governments and serve as an auxiliary to the National Guard. Except in times of extreme national emergency, such as a mainland invasion of the United States, State Militias are operated independently from the U.S. Army and are seen as state government agencies rather than a component of the military.

Although the present-day Army exists as an all volunteer force, augmented by Reserve and National Guard forces, measures exist for emergency expansion in the event of a catastrophic occurrence, such as a large scale attack against the U.S. or the outbreak of a major global war.

The final stage of Army mobilization, known as "activation of the unorganized militia" would effectively place all able bodied males in the service of the U.S. Army. The last time an approximation of this occurred was during the American Civil War when the Confederate States of America activated the "Home Guard" in 1865, drafting all males, regardless of age or health, into the Confederate Army.

Structure

The United States Army is made up of three components: the active component, the Regular Army; and two reserve components, the Army National Guard and the Army Reserve. Both reserve components are primarily composed of part-time soldiers who train once a month, known as Battle Assembly or Unit Training Assemblies (UTAs), and conduct two to three weeks of annual training each year. Both the Regular Army and the Army Reserve are organized under Title 10 of the United States Code, while the National Guard is organized under Title 32. While the Army National Guard is organized, trained and equipped as a component of the U.S. Army, when it is not in federal service it is under the command of individual state and territorial governors, and the Mayor of the District of Columbia. However the National Guard can be federalized by presidential order and against the governor's wishes.[19]

The U.S. Army is led by a civilian Secretary of the Army, who reports to the Secretary of Defense, and serves as civilian oversight for the U.S. Army Chief of Staff. The Army Chief of Staff is a member of the Joint Chiefs of Staff, a body composed of the service chiefs from each service who advise the President and Secretary of Defense on military matters under the guidance of the Chairman and Vice Chairman of the Joint Chiefs of Staff.

In 1986, the Goldwater-Nichols Act mandated that operational control of the services follows a chain of command from the President to the Secretary of Defense directly to the Unified Combatant Commanders, who have control of all armed forces units in their geographic or function area of responsibility. Thus, the Chief of Staff of each service only has the responsibility to organize, train and equip his own service component. The services provide trained forces to the Combatant Commanders for use as they see fit.

Through 2013, the Army is shifting to six geographical commands that will line up with the six geographical Unified Combatant Commands (COCOM):

Each command will receive a numbered army as operational command, except U.S. Army Pacific, which will have a numbered army for U.S. Army forces in the Republic of Korea.

The Army is also changing its base unit from divisions to brigades. When finished, the active army will have increased its combat brigades from 33 to 48, with similar increases in the National Guard and Reserve forces. Division lineage will be retained, but the divisional HQs will be able to command any brigades, not just brigades that carry their divisional lineage. The central part of this plan is that each brigade will be modular, i.e. all brigades of the same type will be exactly the same, and thus any brigade can be commanded by any division. There will be three major types of ground combat brigades:

  • Heavy brigades will have about 3,700 troops and be equivalent to a mechanized infantry or tank brigade.
  • Stryker brigades will have around 3,900 troops and be based around the Stryker family of vehicles.
  • Infantry brigades will have around 3,300 troops and be equivalent to a light infantry or airborne brigade.

In addition, there will be combat support and service support modular brigades. Combat support brigades include Aviation brigades, which will come in heavy and light varieties, Fires (artillery) brigades, and Battlefield Surveillance Brigades. Combat service support brigades include Sustainment brigades and come in several varieties and serve the standard support role in an army.

Regular combat maneuver organizations

The U.S. Army currently consists of 10 active divisions as well as several independent units. The force is in the process of growth, with four additional brigades scheduled to activate by 2013, with a total increase of 74,200 soldiers from January 2007. Each division will have four ground maneuver brigades, and will also include at least one aviation brigade as well as a fires brigade and a service support brigade. Additional brigades can be assigned or attached to a division headquarters based on its mission.

Within the Army National Guard and the Army Reserve there are a further six divisions, over fifteen maneuver brigades, additional combat support and combat service support brigades, and independent cavalry, infantry, artillery, aviation, engineer, and support battalion. The Army Reserve in particular provide virtually all psychological operations and civil affairs units.

Personnel

These are the U.S. Army ranks and their equivalent NATO designations.

Commissioned Officers:[20]

There are several paths to becoming a commissioned officer including Army ROTC, the United States Military Academy at West Point or the United States Merchant Marine Academy at Kings Point, and Officer Candidate School. Certain professionals, physicians, nurses, lawyers, and chaplains are commissioned directly into the Army. But no matter what road an officer takes, the insignia are the same.

The highest officer rank is the five-star general (General of the Army) and the lowest is the second lieutenant.

Address all personnel with the rank of general as "General (last name)" regardless of the number of stars. Likewise, address both colonels and lieutenant colonels as "Colonel (last name)" and first and second lieutenants as "Lieutenant (last name)."

Warrant Officers:[20]

Warrant Officers are single track, specialty officers with subject matter expertise in a particular area. They are initially appointed as warrant officers (in the rank of WO1) by the Secretary of the Army, but receive their commission upon promotion to Chief Warrant Officer Two (CW2).

Technically, warrant officers are to be addressed as "Mr. (last name)" or "Ms. (last name)." However, many personnel do not use those terms, but instead say "Sir", "Ma'am", or most commonly, "Chief".

Enlisted Personnel:[20]

Sergeants are referred to as NCOs, short for non-commissioned officers. Corporals are also called "hard stripes", in recognition of their leadership position. This distinguishes them from specialists who might have the same pay grade, but not the leadership responsibilities.

Address privates (E1 and E2) and privates first class (E3) as "Private (last name)." Address specialists as "Specialist (last name)." Address sergeants, staff sergeants, and sergeants first class as "Sergeant (last name)." Address higher ranking sergeants by their full ranks in conjunction with their names.

All Sergeant ranks from E-5 SGT to E-8 MSG are simply referred to as "Sergeant (last name)". First Sergeant as "First Sergeant (last name)", Sergeant Major, Command Sergeant Major, and Sergeant Major of the Army as "Sergeant Major (last name)". Privates are usually referred to simply by their last names.

Training

Training in the United States Army is generally divided into two categories – individual and collective.

Basic training consists of 9 weeks for most recruits followed by AIT (Advanced Individualized Training) where they receive training for their MOS with the length of AIT school varying by the MOS. Individuals who have the MOS 11B (infantry) go to 14 weeks of OSUT (One Station Unit Training) at Fort Benning, Georgia. OSUT counts as basic and AIT for infantry soldiers. Individual training for enlisted soldiers usually consists of 14 weeks for those who hope to hold the Military Occupational Specialty for infantryman, MOS 11B. Other combat MOSs consist of similar training length. Support and other MOS hopefuls attend nine weeks of Basic Combat Training followed by Advanced Individual Training in their primary (MOS) at any of the numerous MOS training facilities around the country. The length of time spent in AIT depends on the MOS of the soldier. Depending on the needs of the Army BCT is conducted at a number of locations, but two of the longest running are the Armor School at Fort Knox, Kentucky and the Infantry School at Fort Benning, Georgia. For officers this training includes pre-commissioning training either at USMA, ROTC, or OCS. After commissioning, officers undergo six weeks of training at the Basic Officer Leaders Course, Phase II at Ft. Benning or Ft. Sill, followed by their branch specific training at the Basic Officer Leaders Course, Phase III (formerly called Officer Basic Course) which varies in time and location based on their future jobs.

Collective training takes place both at the unit's assigned station, but the most intensive collective training takes place at the three Combat Training Centers (CTC); the National Training Center (NTC) at Fort Irwin, California, the Joint Readiness Training Center (JRTC) at Fort Polk, Louisiana, and the Joint Multinational Training Center (JMRC) at the Hohenfels Training Area in Hohenfels, Germany.

Six Sigma Training

The largest business transformation attempted to date was by the United States Army and its 1.3 million employees. Six Sigma first found its way into the Army in 2002 in the Army Material Command division, which is responsible for purchasing virtually everything in the army, from cornmeal to aircraft. Efficiencies from Six Sigma achieved in this department, a few others, as well as an increasingly disproportional amount of demands compared to funds post 9/11, led to an army wide implementation of the program in late 2005.[21]

After careful consideration, the army decided to implement the program the way the army does everything: centrally plan and de-centrally execute. Army generals and members of the government went behind closed doors for two days, learning their responsibilities of the implementation and the benefits they will achieve. Army employees with leadership roles were asked to define areas their departments were experiencing problems in as well as identify key personnel they felt were capable of learning Six Sigma. Eventually, the lowest ranking employees were asked to define the largest problems they faced on a day to day basis, and the answers were sent to the Army generals who, with the help of Six Sigma, strategically developed and proposed proper solutions.[21]

Army employees were trained in Six Sigma through the use of experts. Since training began in June 2006, they have trained 1,240 Green Belts, 446 Black Belts, and 15 Master Black Belts; completed 1,069 projects; and managed to save nearly two billion dollars to date. The army realized such huge savings by implementing new, more efficient methods, eliminating waste as well as the elimination of non-value adding activities.[21]

Many improvements in the Army’s business processes should be credited to the vast improvements in efficiency. In particular, the dramatic effect Six Sigma has had on eliminating redundancies in efforts and resources has resulted in savings nearly a quarter of their cost. Productivity has increased and costs have decreased because of such eliminations, resulting in a more financially secure Army. New software uncovered that the Army was paying to provide foreign language instruction to a substantial number of non army personnel; this discovery, followed by the restructuring of the program, saved the Army $400 million the following year. Other Six Sigma improvements, saving the Army millions, include streamlining the recruiting process, preventing food waste at West Point, and improving foreign military sales. Such successes enjoyed by the Army have recently lead to the full implementation of Six Sigma by both the Air Force and Navy, as well as initiating talks with the Secretary of Defense to incorporate lean Six Sigma throughout the entire department.[21]

Equipment

Weapons

The Army employs various individual weapons to provide light firepower at short ranges.

The M16 series assault rifle[22] and its compact variant, the M4 carbine,[23] which is slowly replacing selected M16 series rifles in some units and is primarily used by infantry, Ranger, and Special Operations forces.[24] Soldiers whose duties require a more compact weapon, such as combat vehicle crew members, staff officers, and military police, are issued a sidearm in lieu of a rifle. The most common sidearm in the U.S. Army is the 9 mm M9 pistol[25] which is issued to the majority of combat and support units.

Many combat units' arsenals are supplemented with a variety of specialized weapons, including the M249 light machine-gun, to provide suppressive fire at the fire-team level,[26] the M1014 Joint Service Combat Shotgun or the Mossberg 590 Shotgun for door breaching and close-quarters combat, the M14 rifle for long-range marksmen, and the M107 Long Range Sniper Rifle, the M24 Sniper Weapon System, or the M110 Semi-Automatic Sniper Rifle for snipers. Hand grenades, such as the M67 fragmentation grenade and M18 smoke grenade, are also used by combat troops.

The Army employs various crew-served weapons to provide heavy firepower at ranges exceeding that of individual weapons.

The M249 is the Army's standard light machine gun. The M240 is the Army's standard medium machine gun.[27]. The 12.7 mm M2 heavy machine gun is used as an anti-material and anti-personnel machine gun. The M2 is also the primary weapon on most Stryker variants and the secondary weapon system on the M1 Abrams. The 40  mm MK 19 grenade machine gun is mainly used by motorized units.[28] It is commonly employed in a complementary role to the M2.

The Army uses three types of mortar for indirect fire support when heavier artillery may not be appropriate or available. The smallest of these is the 60 mm M224, normally assigned at the infantry company level.[29] At the next higher echelon, infantry battalions are typically supported by a section of 81 mm M252 mortars.[30] The largest mortar in the Army's inventory is the 120 mm M120/M121, usually employed by mechanized battalions, Stryker units, and cavalry troops because its size and weight require it to be transported in a tracked carrier or towed behind a truck.[31]

Fire support for light infantry units is provided by towed howitzers, including the 105 mm M119A1[32] and the 155 mm M777 (which will replace the M198).[33]

Vehicles

The U.S. Army spends a sizable portion of its military budget to maintain a diverse inventory of vehicles.

The Army's most common vehicle is the HMMWV, which is capable of serving as a cargo/troop carrier, weapons platform, and ambulance, among many other roles.[34] The M1A2 Abrams is the Army's primary main battle tank,[35] while the M2A3 Bradley is the standard infantry fighting vehicle.[36] Other vehicles include the M3A3 cavalry fighting vehicle, the Stryker,[37] and the M113 armored personnel carrier,[38] and multiple types of Mine Resistant Ambush Protected (MRAP) vehicles.

The U.S. Army's principal artillery weapons are the AN/TWQ-1 Avenger, LAV-AD and the M109A6 Paladin self-propelled howitzer[39] and the M270 Multiple Launch Rocket System (MLRS),[40] both mounted on tracked platforms and assigned to heavy mechanized units.

While the U.S. Army operates a few fixed-wing aircraft, it mainly operates several types of rotary-wing aircraft. These include the AH-64 Apache attack helicopter,[41] the OH-58D Kiowa Warrior armed reconnaissance/light attack helicopter,[42] the UH-60 Black Hawk utility tactical transport helicopter,[43] and the CH-47 Chinook heavy-lift transport helicopter.[44]

Uniforms

Two soldiers wearing the ACU, as well as ACU-patterned patrol cap (left) and boonie hat (right).

The Army Combat Uniform (ACU), which features a digital camouflage pattern and is designed for use in woodland, desert, and urban environments.

The standard garrison service uniform is known as "Army Greens" or "Class-As" and has been worn by all officers and enlisted personnel since its introduction in 1956 when it replaced earlier olive drab (OD) and khaki (and tan worsted or TW) uniforms worn between the 1980s and 1985. The "Army Blue" uniform, dating back to the mid-19th century, is currently the Army's formal dress uniform, but in 2009, it will replace the Army Green and the Army White uniforms (a uniform similar to the Army Green uniform, but worn in tropical postings) and will become the "new" Army Service Uniform, which will function as both a garrison uniform (when worn with a white shirt and necktie) and a dress uniform (when worn with a white shirt and either a necktie for parades or a bow tie for "after six" or "black tie" events). The beret will continue to be worn with the new ACU for garrison duty and with the Army Service Uniform for non-ceremonial functions. The Army Blue Service Cap, formerly allowed for wear by all enlisted personnel, are now only allowed for wear by any soldier ranked CPL or above at the discretion of the commander.

Body armor in all units is the Improved Outer Tactical Vest, which is now being supplemented with a lightweight Modular Body Armor Vest.

Culture

Army birthdays

The U.S. Army was officially founded on 14 June 1775, when the Continental Congress authorized enlistment of riflemen to serve the United Colonies for one year.

Basic branches

  • Infantry, 14 June 1775

Ten companies of riflemen were authorized by a resolution of the Continental Congress on 14 June 1775. However, the oldest Regular Army infantry regiment, the 3rd Infantry Regiment, was constituted on 3 June 1784, as the First American Regiment.

  • Adjutant General's Corps, 16 June 1775

The post of Adjutant General was established 16 June 1775, and has been continuously in operation since that time. The Adjutant General's Department, by that name, was established by the act of 3 March 1812, and was redesignated the Adjutant General's Corps in 1950.

  • Corps of Engineers, 16 June 1775

Continental Congress authority for a "Chief Engineer for the Army" dates from 16 June 1775. A corps of Engineers for the United States was authorized by the Congress on 11 March 1789. The Corps of Engineers as it is known today came into being on 16 March 1802, when the President was authorized to "organize and establish a Corps of Engineers … that the said Corps … shall be stationed at West Point in the State of New York and shall constitute a Military Academy." A Corps of Topographical Engineers, authorized on 4 July 1838, was merged with the Corps of Engineers on March 1863.

  • Finance Corps, 16 June 1775.

The Finance Corps is the successor to the old Pay Department, which was created in June 1775. The Finance Department was created by law on 1 July 1920. It became the Finance Corps in 1950.

  • Quartermaster Corps, 16 June 1775

The Quartermaster Corps, originally designated the Quartermaster Department, was established on 16 June 1775. While numerous additions, deletions, and changes of function have occurred, its basic supply and service support functions have continued in existence.

  • Field Artillery, 17 November 1775

The Continental Congress unanimously elected Henry Knox "Colonel of the Regiment of Artillery" on 17 November 1775. The regiment formally entered service on 1 January 1776.

  • Armor, 12 June 1776

The Armor branch traces its origin to the Cavalry. A regiment of cavalry was authorized to be raised by the Continental Congress Resolve of 12 December 1776. Although mounted units were raised at various times after the Revolution, the first in continuous service was the United States Regiment of Dragoons, organized in 1833. The Tank Service was formed on 5 March 1918. The Armored Force was formed on 10 July 1940. Armor became a permanent branch of the Army in 1950.

  • Ordnance Corps, 14 May 1812

The Ordnance Department was established by act of Congress on 14 May 1812. During the Revolutionary War, ordnance material was under supervision of the Board of War and Ordnance. Numerous shifts in duties and responsibilities have occurred in the Ordnance Corps since colonial times. It acquired its present designation in 1950.

  • Signal Corps, 21 June 1860

The Signal Corps was authorized as a separate branch of the Army by act of Congress on 3 March 1863. However, the Signal Corps dates its existence from 21 June 1860, when Congress authorized the appointment of one signal officer in the Army, and a War Department order carried the following assignment: "Signal Department--Assistant Surgeon Albert J. Myer to be Signal Officer, with the rank of Major, 27 June 1860], to fill an original vacancy."

  • Chemical Corps, 28 June 1918

The Chemical Warfare Service was established on 28 June 1918, combining activities that until then had been dispersed among five separate agencies of Government. It was made a permanent branch of the Regular Army by the National Defense Act of 1920. In 1945, it was redesignated the Chemical Corps.

  • Corps of Military Police, 26 September 1941

A Provost Marshal General's Office and Corps of Military Police were established in 1941. Prior to that time, except during the Civil War and World War I, there was no regularly appointed Provost Marshal General or regularly constituted Military Police Corps, although a "Provost Marshal" can be found as early as January 1776, and a "Provost Corps" as early as 1778.

  • Transportation Corps, 31 July 1942

The historical background of the Transportation Corps starts with World War I. Prior to that time, transportation operations were chiefly the responsibility of the Quartermaster General. The Transportation Corps, essentially in its present form, was organized on 31 July 1942. The Transportation Corps is headquartered at Fort Eustis, VA under the mantra "Spearhead of Logistics" and command of Brigadier General Brian R. Layer.

  • Military Intelligence Corps, 1 July 1962

Intelligence has been an essential element of Army operations during war as well as during periods of peace. In the past, requirements were met by personnel from the Army Intelligence and Army Security Reserve branches, two-year obligated tour officers, one-tour levies on the various branches, and Regular Army officers in the specialization programs. To meet the Army's increased requirement for national and tactical intelligence, an Intelligence and Security Branch was established in the Army effective 1 July 1962, by General Orders No. 38, 3 July 1962. On 1 July 1967, the branch was redesignated as Military Intelligence.

  • Air Defense Artillery, 20 June 1968.

Separated from the Field Artillery and established as a basic branch on 20 June 1968, per General Order 25, 14 June 1968.

  • Aviation, 12 April 1983

Following the establishment of the U.S. Air Force as a separate service in 1947, the Army began to develop further its own aviation assets (light planes and rotary wing aircraft) in support of ground operations. The Korean War gave this drive impetus, and the war in Vietnam saw its fruition, as Army aviation units performed a variety of missions, including reconnaissance, transport, and fire support. After the war in Vietnam, the role of armed helicopters as tank destroyers received new emphasis. In recognition of the growing importance of aviation in Army doctrine and operations, Aviation became a separate branch on 12 April 1983, and a full member of the Army's combined arms team.

  • Special Forces, 9 April 1987

The first Special Forces unit in the Army was formed on 11 June 1952, when the 10th Special Forces Group was activated at Fort Bragg, North Carolina. A major expansion of Special Forces occurred during the 1960s, with a total of eighteen groups organized in the Regular Army, Army Reserve, and Army National Guard. As a result of renewed emphasis on special operations in the 1980s, the Special Forces Branch was established as a basic branch of the Army effective 9 April 1987, by General Orders No. 35, 19 June 1987.

  • Civil Affairs Corps, 17 August 1955 (special branch); 16 October 2006 (basic branch)

The Civil Affairs/Military Government Branch in the Army Reserve Branch was established on 17 August 1955. Subsequently redesignated the Civil Affairs Branch on 2 October 1955, it has continued its mission to provide guidance to commanders in a broad spectrum of activities ranging from host-guest relationships to the assumption of executive, legislative, and judicial processes in occupied or liberated areas. Became a basic branch per General Order 29, 12 January 2007.

  • Psychological Operations, 16 October 2006

Established as a basic branch per General Order 30, 12 January 2007.

Special branches

  • Army Medical Department, 27 July 1775

The Army Medical Department and the Medical Corps trace their origins to 27 July 1775, when the Continental Congress established the Army hospital headed by a "Director General and Chief Physician." Congress provided a medical organization of the Army only in time of war or emergency until 1818, which marked the inception of a permanent and continuous Medical Department. The Army Organization Act of 1950 renamed the Medical Department as the Army Medical Service. On June , 1968, the Army Medical Service was redesignated the Army Medical Department.

The legal origin of the Chaplain Corps is found in a resolution of the Continental Congress, adopted 29 July 1775, which made provision for the pay of chaplains. The Office of the Chief of Chaplains was created by the National Defense Act of 1920.

  • Judge Advocate General's Corps, 29 July 1775

The Office of Judge Advocate of the Army may be deemed to have been created on 29 July 1775, and has generally paralleled the origin and development of the American system of military justice. The Judge Advocate General's Department, by that name, was established in 1884. Its present designation as a corps was enacted in 1948.

Values

In the mid to late 1990s, the Army officially adopted what have come to be known as "The 7 Army Core Values." The Army began to teach these values as basic warrior traits. The seven Army Core Values are as follows:

  1. Loyalty – Bear true faith and allegiance to the U.S. Constitution, the Army, your unit, and fellow Soldiers.
  2. Duty – Fulfill your obligations.
  3. Respect – Treat others as they should be treated.
  4. Selfless Service – Put the welfare of the nation, the Army, and your subordinates before your own.
  5. Honor – Live the Army Values.
  6. Integrity – Do what's right, both legally and morally.
  7. Personal Courage – Face fear, danger, or adversity, both physical and moral.

The values were arranged to form the acronym LDRSHIP (leadership).[45]
