Yes, you need to be an officer to fly any type of military airPlane, helicopters are different, you just sign up for it throught the army and they send you to warrant officer school. If you go into ROTC and graduate and then join the airforce you can fly fighters but you will be very lucky if you do. The best bet for flight of any type is the academy. I'm not sure if this is entirely aacurate , but something around half of the pilots that the air force traines come from the academy. But if you do go for ROTC and then try to get into UPT, get ur private pilots license first, BEFORE you join up, it shows that you are serous about flying and it gives you an edge over the other when applying for UPT(undergraduate pilot training).
