The uniform was tested in Italy in 1943 but some GIs claim that non-combatant officers and enlisted personnel would use their position in the rear to get the new uniform, delaying the ultimate field testing in Italy for some time longer. This, along with shipping delays after D-Day kept this uniform from widespread use in Europe until late 1944. After D-Day, Paratroopers were issued complete M1943 uniforms, and infantry units began getting the uniform parts here and there.
