First of all, congrats, man. Sounds like you have a helluva little girl, there. You must be proud.
I don't know the first thing about med school except that it's very competitive. Going on instinct, I'd think your first bet is talk to your family doctor, and see what he or she says about your daughter's application to med schools.
I would also think she being military bound would be a definite perk - as it would show she's good under pressure. Surely ROTC might have some ideas for her.
Sorry I can't offer more, Fint. But damn! Med school for your kid. Hey, you've done something right.
