6 Years after wings.
You will have to go to basic then OCS which will take 6 months. then go to Aviation Officer Basic Course which is another 4 months or so. After AOBC you will start flight school. Both AOBC and IERW (Army UPT) are at Mother Rucker Alabama. Flight school will take around a year. So bascially after basic, OCS, and flight school you will have been in the Army about 2 years, then theres 6 yr commitment after flight school. So by the time you seperate you will have about 8 yrs of service.
