Shields
A shield is a piece of personal armour held in the hand, which may or may not be strapped to the wrist or forearm. Shields are used to intercept specific attacks, whether from close-ranged weaponry like spears or long ranged projectiles such as arrows. They function as means of active blocks, as well as to provide passive protection by closing one or more lines of engagement during combat. Shields vary greatly in size and shape, ranging from large panels that protect the user's whole 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 (like the roromaraugi or qauata). Finally, shields vary greatly in shape, ranging in roundness to angularity, proportional length and wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A gas mask is a piece of personal protective equipment used to protect the wearer from inhaling airborne pollutants and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face.

Rock Throwing
Stone throwing or rock throwing, when it is directed at another person (called stone pelting in India), is often considered a form of criminal battery. In certain political contexts, stone-throwing is considered a form of civil resistance. History The throwing of rocks or stones is one of the most ancient forms of ranged-weapon combat, with stone-throwing slings found among other weapons in the tomb of Tutankhamen, who died about 1325 BC. Xenophon mentions the petrobóloi () in his work '' Hellenica'', and Thucydides and Cassius Dio both mention the lithobóloi () in ''History of the Peloponnesian War'' and ''Histories'' respectively. Both terms mean stone-throwers in Ancient Greek, as army units.
