Lawyers can commission directly as captains in the USAF (and probably other branches) as long as they are not too old and can pass the fitness test. I think they also have to have passed a bar exam in one state, but it doesn't matter which one. They can get up to $65k of student loans repaid and don't even have to go through the same basic training as everyone else.
So (b) is slightly less trivial than saying a successful lawyer would not make captain in the military because most lawyers are one conversation, a few signatures, and one oath away from being a captain.
So don't delay lawyers, join today!
