What's the deal with the GI Bills?

Okay, I know there is a new GI Bill coming into effect in a few months (I think in August 2009) and I was planning on the doing a ROTC Scholarship in college and I was wondering if the GI Bill pertains only to one branch or the military in general. I think it's all military but I just want to be sure.
