I am a ROTC scholarship hopeful. If I get the scholarship, and I do 4 years of school can I choose between competing for active duty or NG/reserves or am I already locked into to having to compete for active duty? I have not made my mind up between NG or active in that case. But, say I do not get the scholarship, and I enlist in NG college first program. How does that work? In this case I would rather do NG as a part-time along with my other career? In already know that you are locked in for those first two years in the program, but then once you "sign" in ROTC you get the other two years through a possible GRFD scholarship?
