Lot's of good stuff on the DD214's. If he's active duty (doubtful) he SHOULD have a military ID he can show to support his claim. Spec Ops in Oklahoma? What branch is he proclaiming to be in? Closest secret squirrel post I can think of is Bragg. Ft. Sill is an artillery post. All the Air Force Bases are not special forces, to my knowledge. Unless the have a detachment of SEALs at Tinker, I think he's full of crap. Even Ft. Smith isn't spec.
I know for a fact there is one E-6 75 RGR actively posted at Ft.Sill....
