In the Guard you can pick your training BEFORE you go, serve your country, get money for furthering your education, and work a civillian job as well. And there is A LOT of traing that could help you as a cop. Combat Medic, Nuclear/Biological/Chemical Specialist, Ordinance Disposal, etc.
Lots of perks for joining the Guard. The Marines don't need perks. They're the Marines.
