What branch of the military do you make the most money at?

The Massachusetts Air and Army National Guard. You can go to any MA state school with your tuition and fees paid for. You are granted 130 credit hours at any collegiate level as well. In other Words, if you already have an associates degree, you can take these credits to earn your masters. You also collect GI bill benefits and do not have to be a state resident to use these benefits.

In terms of straight cash, the Army has the market cornered right now.
