First, please try to use capitalization in your sentences: makes it easier to read.
I've never been an AFPC guy, but I deal with them daily on U-2 assignments. When I can't get a guy released, it's usually for one of three reasons:
--he's already been tapped to go to another assignment (oftentimes, a Predator);
--he upgraded to IP recently, and they need "payback" on the training
--he's in a community that is short manned in his crew position (Aircraft Commander, IP, etc..)
Example: we had a bomber pilot apply and we wanted to interview. Had the support of his Wing CC. AFPC said "no, he's going to the FTU, since he's a young IP, and we're short of IP's." AFPC went back to his OG, and a week later, his Wing reversed their position, and he PCS'd shortly thereafter to his FTU. Hopefully, he'll reapply after his FTU tour.
