Should I enlist before going into a federal agency?

Would it benefit me if I enlisted as MOS 35F, (Intelligence), before I joined any federal agency. I want to go into something similar to intelligence.

I also plan on getting an internship while in college with an agnecy
Update: I don't want to join as an officer because if I enlist I can get intelligence, as oppose to being put where the military wants you if your an officer.
