Marine Corps Officer or Marine Corps Enlisted?

I graduate from Community College May 2010 with an ociates of Science in Criminal Justice. I have a 3.34 overall GPA. Most likely Ill still enlist under the DEP this october for Military Police hopefully volunteering and being selected for K9! For some reason recently I have been thinking alot about becoming an Officer. Northeastern University has a great CJ program and i was wondering if there is an NROTC program or something like that? Would the USMC pay for the rest of my college if I commited as an Officer? Should I be patient and go for the B.S. Degree and become an officer or enlist? Any advice or information that you have for me will be appreicated? Thanks for the help, JARED
