I was in the Marines during the Vietnam war. No squirrels. No F117s. No PC keyboards. Never would have heard "squirrels".
In the 80's, no Marines at Stinker Field, no squirrels, and, I was not in the Air Force. Just a very well paid vet.
So I don't know what you are trying to prove and I cannot fathom why the hell you are trying so hard to prove it?
