A small distinction there. He said he spent a year in a "war zone". A tiny bit of honesty creeping into his narrative in that he never actually served in combat. You get the same thing with the Viet Nam "era" vets.
Many years ago, someone did a break down of the numbers.
When it finally got to the point of actually "seeing, and firing upon", the opponent, the percentage was exceedingly small.
I have no clue as to accurate it was. I just recall being surprised.
It was very, very small, compared to total numbers.
