Not all AFROTC detachments are created equal. After talking to guys in my UPT class they all made it seem like it wasn't that hard to get a pilot slot out of ROTC. They did say that it was hard to get into ENJJPT but they all got it so maybe they were in the top of their class. But it seemed like the guys in ROTC at my college kept getting Navs and ABM spots but no pilot slots. So I guess it would depend on where you got to college. I have no idea how all that works as I am guard, just realying what I have seen and heard. Best of luck!
