boots because they were less likely to snag on their parachute when it deployed. The cotton sateen trousers were modified in 1944 with the addition of trouser cuff tabs and again in a 1945 pattern with minor cut modifications and a move from stud to plastic buttons. Postwar impact A new uniform, known as OG-107, was first introduced in 1952. By the beginning of the Vietnam War, it had completely replaced the M-1943 uniform as the standard in the Army. The 1943 pattern jacket was issued to soldiers all the way through the Korean War but was superseded by the 1950 pattern which changed to a button-in liner, then further modified as the 1951 pattern which added bi-swing shoulder pleats, and the use of zippers and snap fastener. The latest version of the jacket, the M-1965 field jacket, is still in service, though now made of a tougher cotton/nylon blend with polyester fill in the liner, and comes in the modern Army Operational Camouflage Pattern. It is no longer used for combat operations having been superseded by the Gen II and Gen III Gore-Tex parkas.
