Yes. She knew already. I'm not sure if she wanted to serve full time or not. There was and is nothing stopping her. They go through the same training as full time service members. She would just have to make a request. Once you're in the military you even have the opportunity to switch branches. I just remembered, she plays trumpet. That's her military job. Anyways, I guess I'd have to ask her to be sure but my guess is that she actually prefers being in the guard.
Yeah, I'd say you're right. It was her dream afterall.
