Its been a while since I applied but there is an application package you have to fill out with recommendations. I also had to do an interview with the Officer recruiter. I would suggest contacting an Officer recruiter so he can lead you down the right path.

I went the NROTC route. I was just as prepared as my Boat School peers for flight school. Its all a personal choice as to where you want to get your education, provided you have the choice.
