A shield is a type of personal armor, meant to intercept attacks, either by stopping projectiles such as arrows or redirecting a hit from a sword, mace or battle axe to the side of the shield-bearer.

Shields vary greatly in size, ranging from large panels that protect the user's entire body to small models (such as the buckler) that were intended for hand-to-hand-combat use. Shields also vary a great deal in thickness; whereas some shields were made of relatively deep, absorbent, wooden planking to protect soldiers from the impact of spears and crossbow bolts, others were thinner and lighter and designed mainly for deflecting blade strikes.

In prehistory and during the era of the earliest civilizations, shields were made of wood, animal hide, woven reeds or wicker. In classical antiquity, the Migration Period and the Middle Ages, they were normally constructed of poplar, lime or another split-resistant timber—covered in some instances with leather and/or reinforced with a metal boss, rim or banding—and carried by foot soldiers, knights and cavalry.

Shape wise, depending on time and place, shields could be round, oval, square, rectangular, triangular or scalloped. Sometimes they took on the form of kites, flatirons or figures-of-eight, or had rounded tops on a rectangular base with perhaps an eyehole inserted. The shield was held by a central grip or by straps which went over or around the user's arm

Often shields were decorated with a painted pattern or an animal representation and these designs developed into systematized heraldic devices during high-medieval times for purposes of battlefield identification. Even after the introduction of gunpowder and firearms to the battlefield, shields continued to be used by certain groups. In the 18th century, for example, Scottish Highland fighters liked to wield small shields (known as a targe), and as late as the 19th century, some non-industrialized peoples employed them (such as Zulu warriors) when waging war.

In the 20th and 21st century, shields have been used by military and police units that specialize in anti-terrorist actions, hostage rescue, riot control and siege-breaking. The modern term usually refers to a device that is held in the hand or attached to the arm, as opposed to an armored suit or a bullet-proof vest.

Prehistory and antiquity

The oldest form of shield was a protection device designed to block attacks by hand weapons, such as swords, axes and maces, or Ranged weapon sling-stones and arrows. Shields have varied greatly in construction over time and place. Sometimes shields were made of metal, but wood or animal hide construction was much more common; wicker and even turtle shells have been used. Many surviving examples of metal shields are generally felt to be ceremonial rather than practical, for example the Yetholm-type shields of the Bronze Age or the Iron Age Battersea shield. The shield was used to make the Greek Phalanx formation.

Size and weight varied greatly. Lightly armored warriors relying on speed and surprise would generally carry light shields that were either small or thin. Heavy troops might be equipped with robust shields that could cover most of the body. Many had a strap called a guige that allowed it to be slung over the user's back when not in use or on horseback. During the 14th-13th century BC, the Sards or Shardana, working as mercenaries for the Egyptian pharaoh Ramses II, utilized either large or small round shields against the Hittites. The Mycenaean Greeks used two types of shields: the "figure eight" or "fiddle" shield, and a rectangular type, the "tower" shield, curved on the top. They were made of wood and leather, and were of such a large size that a warrior could hide completely behind his shield. The Ancient Greek hoplites used a round, bowl-shaped wooden shield called an aspis. Examples of Germanic wooden shields c350 BC - 500 AD survive from weapons sacrifices in Danish bogs.

The heavily armored Roman legionaries carried large shields (scuta) that could provide far more protection, but made swift movement a little more difficult. The scutum originally had an oval shape, but gradually the curved tops and sides were cut to produce the familiar rectangular shape most commonly seen in the early Imperial legions. Famously, the Romans used their shields to create a tortoise-like formation called a testudo in which entire groups of soldiers would be enclosed in an armoured box to provide protection against missiles. Many ancient shield designs featured incuts of one sort of another. This was done to accommodate the shaft of a spear, thus facilitating tactics requiring the soldiers to stand close together forming a wall of shields.

Middle Ages

In the early European Middle Ages, simple round shields made from linden-wood wood covered on both sides by leather were typical. Over time, these were displaced by the kite shield, which was rounded at the top and tapered at the bottom. This gave some protection to the user's legs, without adding too much to the total weight of the shield. Kite shields were commonly used by cavalry as well.

As body armour improved, knight's shields became smaller, leading to the familiar heater shield style. Both kite and heater style shields were made of several layers of laminated wood, with a gentle curve in cross section. The heater style inspired the shape of the symbolic heraldic shield that is still used today. Eventually, specialised shapes were developed such as the bouche, which had a lance rest cut into the upper corner of the lance side, to help guide it in combat or tournament. Free standing shields called pavises, which were propped up on stands, were used by medieval crossbowmen who needed protection while reloading.

In time, some armoured foot knights gave up shields entirely in favour of mobility and two-handed weapons. Other knights and common soldiers adopted the buckler (origin of the term "swashbuckler"^[1]). The buckler is a small round shield, typically between 8 and 16 inches (20-40 centimeters) in diameter. The buckler was one of very few types of shield that were usually made of metal. Small and light, the buckler was easily carried by being hung from a belt; it gave little protection from missiles and was reserved for hand-to-hand combat. The buckler continued in use well into the 16th Century.

In Italy, the targa, parma and rotella were utilized by common people, fencers and even knights. The development of plate armour made shields less and less common as plate armour eliminated the need for a shield. Lightly armoured troops continued to use shields after men-at-arms and knights ceased to use them. Shields continued in use even after gunpowder powered weapons made them essentially obsolete on the battlefield. In the 18th Century, the Scottish clans used a small, round shield called a targe that was partially effective against the firearms of the time, although it was arguably more often used against British infantry bayonets and cavalry swords in close-in fighting.

During the 19th Century, non-industrial cultures with little access to guns were still using war shields. Zulu warriors carried large lightweight shields made from a single ox hide supported by a wooden spine, these were called Ishlangu.^[2] This was used in combination with a short spear (assegai) and/or club.

Although the size of shield would vary due to personal preference and role, most were thin compared to common belief (a misconception aided by the depiction of heavy shields in films). When used in fighting, shields were most effective when used to cause glancing blows. By deflecting a sword blow to the side, rather than blocking it head on, the attacker could be rendered open to a counterattack. This technique allowed the shield to be made lighter and more easily wielded, while reducing the amount of energy and risk of injury posed to the shield-bearer.

Shields for protection from armed attack are still used by many police forces around the world. These modern shields are usually intended for two broadly distinct purposes. The first type, riot shields, are used for riot control and can be made from metal or polymers such as polycarbonate Lexan or Makrolon or boPET Mylar. These typically offer protection from relatively large and low velocity projectiles, such as rocks and bottles, as well as blows from fists or clubs. Synthetic riot shields are normally transparent, allowing full use of the shield without obstructing vision. Similarly, metal riot shields often have a small window at eye level for this purpose. These riot shields are most commonly used to block and push back crowds when the users stand in a "wall" to block protesters, and to protect against shrapnel, projectiles, molotov cocktails, and during hand-to-hand combat.

The second type of modern police shield is the bullet-resistant tactical shield. These shields are typically manufactured from advanced synthetics such as kevlar and are designed to be bulletproof, or at least bullet resistant. Two types of shields are available. 1. Light weight level IIIA shields that stop hand guns and submachine guns. 2. Heavy Level III and IV shields that stop rifle rounds. Tactical shields often have a firing port so that the officer holding the shield can fire a weapon while being protected by the shield, and they often have a bulletproof glass viewing port. They are typically employed by specialist police, such as SWAT teams in high risk entry and siege scenarios, such as hostage rescue and breaching gang compounds, as well as in antiterrorism operations. Tactical shields often have a large signs stating "POLICE" (or the name of a force, such as "US MARSHALS") to indicate that the user is a law enforcement officer.

Gun shields

With the widespread use of machine guns in World War I and in subsequent conflicts, battlegrounds were swept with automatic weapons fire. While soldiers who are in foxholes or trenches are protected from this fire, soldiers who are manning mounted machine guns were vulnerable to being hit. Since WW I, there have been a variety of attempts to install armored gun shields on tripod-mounted machine guns or vehicle-mounted weapons to protect machine gunners. Transportation devices with mounted guns that may have gun shields to protect the gunner include jeeps, Humvees, armored cars, and boats.

Non-martial applications

Many non-martial devices also employ shielding of a kind—not usually a single device worn on an arm but various protective plates or other insulation positioned where needed. Space craft have heat shields to ensure a safe re-entry. Electronics uses shielding to reduce electrical noise and crosstalk between signals. Better-quality patch cables used in audio and electronic music have shielding to reduce interference and noise. People and systems that must work in the presence of ionizing radiation (X-rays) such as dentists, hospital technicians, and patients undergoing X-rays are protected with lead shielding clothing.

A "shield" is also a design term used to describe emblems that resemble a heraldic shield. Movie studio Warner Bros. uses a shield emblazoned with WB as its logo. The Looney Tunes cartoons, released through Warner Bros., open with the WB shield zooming through concentric circles.
