Mostly guard duty at various bases and installations. It won't be the most exciting...but if your goal is to be in civilian LE when you get out, its great.
Also, considering your hi gpa, you might want to try for intel. This is one of the more difficult MOS's to get. Ask your recruiter...and hopefully he won't peddle you a load of BS like mine did :D
