Thirty thousand
I was stationed there just under two years ago and I recall 932 sq. miles, largest training area in the world I believe.
The Marine Corps reached a peak strength of over 700,000. There were six Marine Divisions, all infantry, and all fought in the Pacific. There were also a few Air Wings, and some tank battalions. The WWII Marine Corps was about one-tenth the size of the US Army, and fielded about one-fifteenth as many divisions.
You don't. If you are not a Marine or a registered Junior Marine it is illegal to wear any form of military uniform. If you want to wear dress blues outside the privacy of your own home then you must enlist in the Marine Corps, otherwise you could be caught, convicted, and become a felon.
The question seems to be asking in what war the US Marine Corps first fought. The Continental Marines were formed in 1775 to fight the British in the American Revolution, but the US Marine Corps was founded in 1794, and their first opponents were the Pirates of Tripoli. US Marines participated in later wars in small numbers, but they did not actually attain the size of a corps until World War 2.
The Iwo Jima Memorial is located near the Pentagon. It is adjacent to Arlington National Cemetery. It is quite an imposing statue. The base contains a great deal of the information about the history of the Marine Corps.
To base this answer off an objective metric, such as funding, manpower and defined minimum capabilities, the Marine Corps of the United States would hold the title. No other nation maintains a 'force in readiness' by forward deploying a rapid response force in such size and capability within the spectrum of combat. Funding allocated for equipment, training and welfare are second to none. The United States also maintains the largest standing Marine Corps, with over 180,000 active duty Marines.
The United States Marine Corps (USMC) is a branch of the United States armed forces responsible for providing force projection from the sea, using the mobility of the U.S. Navy to rapidly deliver combined-arms task forces. It is one of seven uniformed services of the U.S.. Administratively, the Marine Corps is a component of the Department of the Navy, but it acts operationally as a separate branch of the military, often working closely with US Naval forces for training, transportation, and logistic purposes. Originally organized as the Continental Marines on November 10, 1775 as naval infantry, the Marine Corps has evolved in its mission with changing military doctrine and American foreign policy. The Marine Corps has served in every American armed conflict and attained prominence in the 20th century when its theories and practice of amphibious warfare proved prescient and ultimately formed the cornerstone of the Pacific campaign of World War II. By the mid 20th century, the Marine Corps had become the dominant theorist and practitioner of amphibious warfare. Its ability to respond rapidly to regional crises gives it a strong role in the implementation and execution of American foreign policy. The United States Marine Corps, with 194,000 active duty and 40,000 reserve Marines, is the smallest of the United States' armed forces in the Department of Defense (the United States Coast Guard is smaller, about one fifth the size of the Marine Corps, but serves under Homeland Security). The Corps is nonetheless larger than the entire armed forces of many significant military powers; for example, it is larger than the active duty Israel Defense Forces or the whole of the British Army.
There are typically 15 to 20 captains in a standard Marine Corps company, which can vary depending on the unit's size and structure. Each captain serves as a company commander, leading and managing the unit's operations.
The average size of a whale's brain is larger than most other marine mammals.
The average size of a blue whale's brain is the largest among all marine mammals.
Crinoids, also known as sea lilies, are marine organisms that typically range in size from a few centimeters to several meters in length. On average, crinoids are smaller in size compared to other marine organisms such as whales, sharks, and large fish.
Yes corps of discovery accomplishes its goal. Jefferson provided the best supplies, clothing, firearms and equipment and in 1803 it had doubled in size of the nation.
