He should also consider the opportunity for promotion if he wants to make the military his career. In either service he will be competing with the academy grads, and to some extent pilots. The Air Force's mission is obviously flying, so some people think that anyone other than pilots are second class citizens. My understanding is that the Navy has more promotional opportunities for non-pilots.

Otherwise, I think it comes down to which service has a position open for him and which positions fit his skills and education.
