I was in the USMCR from 1965-1971, I did my active duty in California. I have similar memories of boot camp as SGT GRIT, but I remember my after boot camp training to be, about a month each in Basic Infantry Training, Advanced Infantry Training, and Advanced Combat Training.
The part that I am curious about is the ACT, anybody out there that went through that training in March 1966? Just to jog the memory, I think I remember it being loosely referred to as, special missions. I am curious as to what the regulars did, after they finished with the training? At the time of the training we were told to keep quite about what we were doing, I think enough time has passed, maybe somebody wants to describe it further?
