Your plan for education is a good one. Your willingness to serve your country in time of war is admirable considering how few actually do something good to contribute to the freedoms we enjoy in this great nation. That part is not a long shot, assuming you are physically qualified and pass the enlistment tests to get into a good career field.
I would recommend aircraft maintenance, because you could get on the path to becoming an A & P which is a good thing. I wish I had the time to get that training.
The flight spot is a long shot, but well worth it. As many have said, you can't win, if you don't try to play the game. Once you are in the ANG, don't limit your applications to just your unit. It is ok to try to apply to other ANG/AFR squadrons to try to get a UPT slot. Your odds are better in your own unit, especially if you are a team player, do your job well. But occassionally there won't be enough spots to go around for too many qualified applicants. At 22, time is your friend, but if you get to 26-27 year age mark without a slot, then you need to start applying to other units, if you get dead set on a flying spot.
Good Luck in your quest.
