I might help here.
I was in both the Army and the Air Force (Air Guard).
I was enlisted, got my degree, and decided to become an officer. I had to take the AFOQT. It wasn't that tough and the bar is set pretty low, especially for pilots (unnerving, I know, and one of the reasons I chose to jump out of perfectly good airplanes).
I had to go before a commissioning board. Essentially, they made sure all the ducks were in a row and you had the right frame of mind. I wouldn't call it a rubber stamp, because some people were not recommended.
I had to take a commissioning physical. This is where I got knocked out. They found I had hypertrophic cardiomyopathy with outflow tract obstruction. I never knew because I am asymptomatic (essentially, I live a normal life with no effects). Tried for the waiver, denied, handed my hat 12 years in (no pension of any type).
Had I passed, I would have to go through OTS. The Army's version is brutal from what I hear. When I was at Benning for jump school, I saw them and actually felt sorry for them. The Air Force is much more laid back. So, they put you through the training school and off to the tech school. The follow-on school is where you learn your new job, Depending on your career, it can be as short as six weeks to as long as a year or more.
Without a doubt, the easiest way to get a commission is to plug through college for four years (have them pick up the tab for at least the last two through a ROTC scholarship).
On a related note, I switched to the Air Guard because of quality of life. In the PA Army guard, you train at Ft. Indiantown Gap. Big, open bays that were too hot in the summer and freezing in the winter. Chow was mediocre. Never went anywhere interesting.
In the Air Guard (as enlisted), I had a room, sometimes without a roomate, with air conditioning, maid service, TV/VCR, cable. Food was slightly better. Trips were plentiful. Got to go to Midland, Texas (had a horrible time), Budapest (for the Kosovo Campaign), Puerto Rico (good and bad), and so on. You can jump on flights to Alaska, Hawaii, Europe, etc.
So, in summary, go to college. Work hard, get an AF ROTC scholarship. Join the Air Force. See the world.
