The M-1943 is the most stylish version, and for the US military was a functional step up (several steps-up, actually) from the earlier issue coats like the M-1941 (although not sartorially). I was issued a camo M-65 field jacket while in the U.S. Army, but they were being phased out in the 1990s as Goretex coats were issued. I loved the poly liners for the older field jacket, though!
