You should work on getting as much college done as you can, towards a 4-year degree. With all the breaks and restarts in flight training you'd have to go through, due to deployments/exercises/PCS/being stationed overseas, as well as an often irregular work schedule, it'd just be inefficient, and ultimately wasteful of money and time. It may be possible to get a rating during each of your annual 30-day leave periods, but that's quite a gamble.

Get as much college as you can, and wait until ETS to start flight training.
