Early in WWII, the Army developed two camouflage uniforms. They were made from HBT cotton cloth, printed with double-sided "Spring" and "Fall" color camouflage. (This was the same cloth used by the Marines for their P42 and P44 camouflage uniforms.) Both a coverall and a two piece jacket and trouser were produced.

The coverall was quickly deemed too hot and clumsy to wear. They were issued in very limited numbers in both Europe and the Pacific.

However, the two-piece uniform was more successful and was issued for troop trials in the summer of 1944.
