I'm not military but come from a military family so here's what I got:

My cousin is ANG (kinda) with the 157th Fighter Wing in Hawaii (F-15's). He got accepted into his slot over a year ago and is still fighting to get medical clearance, security clearance, training dates, etc. From what I've seen, long frustrating waits are common but the pay off in the end is worth it. On the flipside, my lady friend got accepted and started training in less than six months, but she was ROTC going into the Army National Guard (blackhawks). But like I said, I'm not military I just know a bunch of them so I could be wrong.
