The tac tray for the coaxial [coax] machinegun mounted on the inside left wall of our M48A5 tanks held 6000 rounds. We often carried enough spare boxes of ammo on the floor in ammo cans [200 rounds each, or if we had enough time to break it down and refill the cans the way we liked, 250 rounds each] to refill that, and outside the tank on the external bustle rack, about half that much again [in a USAF mini-gun ammo can for 3000 rounds] plus extra .50 ammo, and an extra can or two [1000 rounds] of .45 for our pair of M3A1 .45 *greasegun* submachineguns and our half-dozen or so .45 pistols. All told, it added up to a load of around 15,000 rounds for the one coax machinegun. One morning we had fired off that much ammo before noonish lunchtime. It was, as we said in the business, a busy day at the office.
The guy behind the log does NOT have enough ammo. Or spare barrels.
Ammo Chick asks, "Did one of you boys say you were low on ammo?"
