Well you guys have the misfortune of running into the only Vietnam Vet that wasn’t a Special Ops, Seal, CIA, Green Berete, etc. I only told you what the instructors at USSADS told those of us that were being trained in automatic weapons. That was their line at the time and it made sense to me.
I think I was in the last class of conventional ADA, from 5.56 to 40mm Bofors. If you want to shoot tracers in your gun it’s your business.
