The .303 Vickers Gun could fire over 600 rounds per minute and had a range of 4,500 yards. Being water-cooled, it could fire continuously for long periods. There were usually six men in a Vickers gun team. "Number One was leader and fired the gun, while Number Two controlled the entry of ammo belts into the feed-block. Number Three maintained a supply of ammo to Number Two, and Number Four to Six were reserves and carriers, but all the members of the team were fully trained in handling the gun.
