Staff Sergeant Sam Cahoon (Medic, 2d Battalion, 398th Infantry Regiment) in camouflage fatigues during Tennessee Maneuvers, December 1943.

Although the multi-hue woodland pattern was quite useful for helping its wearers blend into the background, the first units to wear them in combat in Normandy found themselves subjected to significant "friendly fire casualties," due to the similarity of the pattern to that worn by soldiers of the Waffen-SS. These uniforms were quickly withdrawn from service in the summer of 1944, and as a result, no one from the 100th Infantry Division ever wore this uniform in combat.
