<sod>The 1943 pattern uniform was superseded by the 1950 pattern from 1950 which simply changed to a button-in liner.  The jacket of the 1951 pattern uniform owes much to the 1943 pattern but uses bi-swing pleats, the use of zip and stud fastening. The 1951 pattern trousers are of new design. The 1965 pattern closely follows the 1951 pattern. The latest version of the jacket, the M-65, is still in service, and differs from the M-1943 in that now it is made of a tougher cotton/nylon mix and comes in the new Army [[digital camouflage]]. It is no longer used for combat operations having been superseded by the Gen II and Gen III [[Gore-Tex]] parkas.<ref name=OliveDrab /><eod>
