If you want to are dead set on being in the service as an officer, I would shoot for an NROTC scholarship, or starting at college with a unit and trying to pick up a scholarship (you have until the end of your sophomore year). If you are looking to get away for personal reasons, maybe do what my father did and do dual full time college student and part time military via the Air Guard. They paid for his expenses, and then he only owed a small commitment of two years by the time he graduated. At that time you could get out and put in for OCS.
