If she is seriously talking to a recruiter, tell her to investigate her options and negotiate for what she wants to be. There are programs the Air Force will pay for. For example, if she wants to go to dental school it's possible they will "swear" her in, she becomes a member of the Air Force, she goes through basic training, and they send her to school. After she completes her education she would be committed to give the AF 3-4 years afterward. But it addition, having a degree she would go in as an officer as opposed to going in as an enlistee.
Sew, tell her to negotiate. They want good people.
