Most units require a cover letter with application packages. It may be a good idea for you to address your GPA issue in that. If I were you, I'd call up the unit(s) you're interested in and start rushing them. Once you get to know the bros in the squadron, bring up your low GPA to the sqcc, do, chief pilot or someone who's going to have some pull in the hiring process. Make friends with the Lt or Capt who's collecting packages too (everyone loves booze). I guarantee you that units would take a good dude with a 2.31 over an asshat with a 4.0.

ANG4me, don't rule out AFRC: very similar to the ANG, except there is no obligation to the Governor. AFRC units still do help with disasters (airlift people out ahead of a hurricane, etc). Some say that the ANG avoids the Active Duty BS better than the Reserves do, but I'm not in a position to compare.

Best of luck to both of you.
