Military Colleges (VMI, The Citadel, Norwich)?

I know most of the Military Colleges like VMI, The Citadel, and Norwich live a Military lifestyle but is basically a college. My question is, is there a way to win 3 or 4 year scholarships for these colleges? At first I assumed that there was nothing to pay like West Point and Annapolis but I was wrong. Also, would going to a Military College help you get the MOS you desire? What I'm asking is, would you have a better chance at getting the MOS you want before regular ROTC graduates from other Universities like in Minnesota or California get their MOS? I know it's an ROTC thing in the Military Colleges but I was just wondering since the whole College lives a Military lifestyle that they'd be ahead of the curb.
