We are not sure how he became a Marine Sniper during his 47 days in the Air Force.
Our friends over at thisainthell.us posted this fellow Gareth Garrison who claims that he was a Marine, and, of course, a sniper; He hangs out at the local VA.
He spent 47 days in the Air Force…kinda the same thing as a Marine Sniper right?
