We had a NBC E-3 assigned to us for a while who said he'd made E-6 in the Marines after 4 years and the decided to join the Army. Anyone who has served in the Marines will tell you making E-6 that fast is rare. We got tired of listening to it after a while and made him bring in his DD-214 and it turned out he was dropped out of the NG before even attending AIT.
Thing is he was a smart kid and a pretty decent NBC guy, but he was always trying to build himself up to be more than he was.
