National Guard has what's called Recruit Sustainment Program (RSP), I've drilled three times since I've joined. We basically carry around a fake M-16 and they simulate what basic training will be like. Needless to say, it sucks, but I love it. My secret clearance took 4 months, I'm sure a TS clearance can take awhile. Are you becoming a linguist that includes being a flight crew member?
