The Vickers machine gun or Vickers gun is a name primarily used to refer to the water-cooled .303 inch (7.7 mm) machine gun produced by Vickers Limited, originally for the British Army. The machine gun typically required a six- to eight-man team to operate: one to fire, one to feed the ammunition, and the rest to help carry the weapon, its ammunition and spare parts. It served from before the World War I until after the end of the World War II.
