* * *IWeapon consisting essentially of a metal tube from which a missile or projectile is shot by the force of exploding gunpowder or some other propellant.The term is often limited today to the so-called big guns, cannon larger than a howitzer or mortar. It may also be used to refer to military small arms such as the rifle, machine gun, and pistol, as well as to nonmilitary firearms such as the shotgun. Though the Chinese used gunpowder in warfare from the 9th century, guns were not developed until the Europeans acquired gunpowder in the 13th century. The earliest guns (с 1327) resembled old-fashioned soda bottles; they apparently were fired by applying a red-hot wire to a touchhole drilled through the top. Separating the barrel and the powder chamber resulted in breechloaders, which continued to be used in naval swivel guns and fortress wallpieces well into the 17th century. Small arms, as distinguished from hand cannon, did not exist until the development of the matchlock in the 15th century. See also flintlock, wheel lock.II(as used in expressions)Machine Gun KellyTaewon gun
* * *▪ weaponweapon consisting essentially of a metal tube from which a missile or projectile is shot by the force of exploding gunpowder or some other propellant. In military science, the term is often limited to cannon larger than a howitzer or mortar, although these latter two types, like all tube-fired artillery pieces, also fall within the general definition of a gun. Guns also include such military small arms as the musket, rifle, machine gun, and pistol, as well as such nonmilitary sport firearms as the shotgun. Bazookas and other rocket launchers, which launch self-propelled projectiles, are not guns, though they perform many of the same functions.Guns of all types are treated in the Macropaedia article War, Technology of (military technology).
