Choices
Just know that aviation is not guaranteed through ROTC. You must accept your commission as an officer before you are given an aviation spot. Then you still have the chance of being a WSO and not a pilot. The military way is a good route because you don't have to pay for your ratings. On the other hand, it is not for everyone. If you choose the military route, I recommend going the Officer Candidate School route(Navy and Marines) or OTS(Air Force). They can guarantee your position before you even go. Look at all of your options before you make a decision though.
