I can only speak for the Air Force. But the other service are probably the same.
You need to join and go thru USAF Pilot Training, about 13 months. You can select to be a FAIP, First Assignment Instructor Pilot, in the T-37, T-6. I don't know about FAIPing to the T-1,T-38. You could when I went through, 1995, but times have changed.
Talk to a recruiter. Better yet try getting a slot in the Air National Guard or Air Force Reserves. Your life will be better and you can still have a civilian career. Call your local ANG unit to find out if they are having a pilot interview board anytime soon.
Good Luck.
