Question about USUHS, oncology, and the military

I'm only in high school, but thinking ahead a bit. I've been reading about this and it's interesting so I wanted to try to clear the air for myself. If I attend USUHS, I get paid to attend med school. I then make a 7 year commitment to the military. Does that commitment essentially serve as my residency and fellowship? Also, is USUHS a good school for oncology? New to all this, so please bear with me. Thanks!
