How can I join the Air Force (or other military forces) as an officer?

You didn't say how much of your degree you have. As it is, 27 is the max age to enlist in the Air force and to become an officer you have to have a 4 year degree. The age limit may be different for the Guard and Reserves because it seems to me that we had girls in my flight that were older than 27 and was in the Guard. But I know for Active Duty the max age is 27.
