Winter Machine Gun Group The M1919 Browning .30 calibre machine gun was widely used in WW2 and was the main company support weapon for GI?s in combat. The gun required at least 2 men to operate and carry it, one to fire the gun, the other to ?feed? the gun. One or two ammunition carriers would also join the team. Our K&C set shows the machine gun in action joined by a squad NCO shouting instructions and carrying a ?Tommy-Gun?.
