For want of enough real arms to train the expanding army, the 71st National Guard regiment gives its recruits preliminary training with dummy guns. One is an imitation of the fifty-caliber machine gun, made of wood and pipes; another, mounted on a rubber-tired truck, is a copy of a thirty-seven millimeter anti-tank gun. Since the guns don't fire, the soldiers are simply taught their theoretical use in maneuvers. Real weapons will replace the dummy guns as fast as they can be produced.
