By April 1951, I had already been USMCR for 2 years; my boot camp days were spent in the 3dRTBn, SDiego. No yellow footprints for years to come, at this point. Also spent time with the 7thRTBn, Separation Bn, and 1stRTBn, before going to NAB, Coronado, with Chesty as CG, in 1953.
The utilities I was issued were of the herringbone type, I remember the full pocket across the seat of my utility trousers, rumored to be grenade pockets? I think my MOS was 0143, later changed to 0141.
