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, battle axe or similar weapon 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 a material such as leather or rawhide and often reinforced with a metal boss, rim or banding. They were carried by foot soldiers, knights and cavalry. Depending on time and place, shields could be round, oval, square, rectangular, triangular, bilobal or scalloped. Sometimes they took on the form of kites or flatirons, or had rounded tops on a rectangular base with perhaps an eyehole. 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 the High Middle Ages 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 (such as Zulu warriors) employed them 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. Shields are also sometimes mounted on vehicle-mounted weapons to protect the operator. == 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 weapons like 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 (''pelte'') 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-of-eight" shield and a rectangular "tower" shield. These shields were made primarily from a wicker frame and then reinforced with leather. Covering the body from head to foot, the figure-of-eight and tower shield offered most of the warrior's body a good deal of protection in man-to-man combat. The Ancient Greek hoplites used a round, bowl-shaped wooden shield that was reinforced with bronze and called an ''aspis''. Another name for this type of shield is a ''hoplon''. The hoplon shield inspired the name for hoplite soldiers. The hoplon was also the longest-lasting and most famous and influential of all of the ancient Greek shields. The Spartans used the aspis to create the Greek phalanx formation. Their shields offered protection not only for themselves but for their comrades to their left and right. Examples of Germanic wooden shields circa 350 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 or 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「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, battle axe or similar weapon 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.
