That first deployment rolls around and she's going to have to settle as the ball and chain while Private/Seaman/Airman/Guardian Snuffy gets his 3 months mistress. Being a dependopotamus is not an enviable existence.
Edit: though, those guys are all desperate (especially the Air Force/Space Force since it's mostly autists) so it should be easy to fish for one right outside the gate of a base. Some might even find the arm flapping as she stands outside extra endearing and choose her over the $2 crack whore.
