LA,
Is the overmanning issue with the AF as bad as some make it to be? Does it look like the issue may be resolved over time?
Would it be better to look into OTS after graduating college, or trying to switch over to AD enlisted after graduating, and then look for a commission later on? I was thinking of trying to switch over to active duty enlisted, after graduating, assuming the AF will take prior service at that time, and completing a masters on the AF's dime, then looking to commission.
