MACHINE-GUN

A machine-gun is an automatically loaded and fired small arm, capable of delivering a continuous stream of fire under the operator's control. Machine-guns are generally divided into three types: sub-machine-gun, a small weapon capable of being carried and operated by a single operator and firing pistol ammunition; light machine-gun, a machine-gun capable of being carried and operated by a single person, larger than a sub-machine-gun and firing larger ammunition, the light machine-gun is usually fired while supported by a bipod or tripod; heavy machine-gun, a larger machine gun with a calibre generally of between 12.7 mm and 20 mm and which requires two or more operatives to carry and fire it.
Classic machine-guns throughout history include: Gatling gun, MG34, MG42, Sten, Bren, Uzi, Madsen Light Machine-gun, Browning Automatic Rifle, Browning M2AA, DShK and Degtyarev DP.
