As a result of this lack of proper and suitable clothing, the Armored units were issued general infantry uniforms, although by 1942 the winter coveralls and winter "tanker" jacket had been produced with them in mind. These articles of clothing were made of light green cotton lined with wool kersey.
The paratroopers got their own unique uniform in 1942, also. It was constructed of light green cotton twill, with four front pockets and two pant-leg cargo pockets. They also got a new boot design of their own, a leather boot of similar construction to the infantry shoe, only being mid-shin high.
Generally speaking though, this was unsatisfactory. The infantry uniform was lacking in functionality compared to the M-1942 Paratrooper uniform, and the tanker winter uniforms were sought after by almost every branch in the Army, making supply and production often difficult.
The combat wool, khaki, and paratrooper trousers all did not have adequate locking stitches in the crotch. Often trousers would tear at that stress point. Also, the paratrooper uniform would tear at the knees and elbows.
The paratroopers tried to fix the problem by sewing canvas patches on the elbows and knees, but the Army sought to standardize a better uniform.
The trousers were made out of the same cotton sateen material and regular cotton twill. They were made similarly to the khaki trousers, with better design features. They also had buttoned tabs at the waist in order to cinch the waist in.
The uniform was designed to be warm in winter by use of a separate jacket liner and pant liner (this is why the trousers had buttoned waist tabs), both made of "pile" faux fur. The trouser pile liners were dropped in favor of ordinary wool trousers. The jacket liner was a separate cotton-shell jacket with two slash pockets and button and loop fastening, generally in a lighter shade of olive drab (OD3) than the main jacket but in practice rarely issued during WW2. In the ETO this was intended to be replaced by the M-1944 'Ike' jacket, or one of the generic 'ETO' jackets which could come in versions that were either near-identical to the M-1941 jacket, but in rough khaki wool outer, or versions almost identical to British Battledress, both versions being produced locally in the UK in several variations.
In all, a number of new items were designed or standardized in 1943 in order to improve the Army uniforms and individual equipment as much as possible:
It was tested in Italy in 1943 but some GIs (including Bill Mauldin) claim that non-combatant officers and enlisted personnel would utilize 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 because of the European orders for the M-1944 "Ike" jacket, kept this uniform from widespread use in Europe until late 1944. After D-Day, Paratroopers were issued complete M-1943 uniforms, and infantry units began getting the uniform parts here and there.
Paratroopers were generally the only ones to modify the uniform, mainly because they would add their own trouser cargo pockets sometimes and would keep their older paratrooper boots instead of the new buckle boots.
The original cotton trousers were modified in 1944 (addition of trouser cuff tabs) and as M-1945 pattern with minor cut modifications and a move from stud to plastic buttons.
In practice the pile liner was very rarely issued outside initial trials in North Africa during WW2 and is mostly seen in photographs worn as outerwear. However it saw use in Korea, although again sometimes as outerwear.
The "Jeep Cap" (Cap, Wool Knit, M-1941) remained in service until the 1950s (any fans of the movie M*A*S*H or the M*A*S*H TV series may remember Cpl. Walter "Radar" O'Reilly wearing one).
The M-1943 goggles were the basic building block development to the M-1944 goggles, which came out the following year.
The combination poncho/tent section would serve in Korea later.
