Part of the challenge is my promotion status. I got passed over for O-5 (one look so far) so the unit can't vacancy promote me. There isn't anything in my record that says don't promote (DUI, no PME, UIF etc.) but if I don't get promoted in the guard, I am in a really bad place to get an airline job. If however the guard promotion is less competitive than the reserve then maybe it's worth a shot.
