I went guard immediately after my discharge in 86, but quit almost as fast. I just wanted a break from the uniform for a while and I never went back. Serving 12 years left me with no time requirement anyway.
I spent a lot of time with the M16, serving my first 5 in the Infantry. Needless to say, it was my best friend. Other than that I ended up with odd weapons. The 90mm recoilless and the M60 were a lot of fun when you had transportation, and I got to play around with the 50cal for a short time. As Tim Taylor would say.. Ohh Ohh Ohh. More Power!
I think I eventually qualified with and could field strip everything they had and earned the EIB, just before switching over to 93H. I get a kick out of people who talk crap. This is not something I normally discuss but I didn't want you to think I was talking out my butt either.
Best.
I'm sorry, my answers are limited. You must ask the right question.
