DD388 Tanker Replacement Corporal

This Tech 5 Corporal has just arrived from the Replacement Depot carrying a bedroll and wearing matching olive drab shirt and trousers and a brand-new shoulder holster rig and pistol which was originally supplied only to Airforce pilots but somehow got to be issued to tank crews and other U.S. Army units. How a lowly noncom got hold of this is anyone's guess.
