Navy Master At Arms require extensive training in order to do their job correctly. "A" school lasts 9 weeks for Masters at Arms, where they learn anti-terrorist techniques, communications, first aid, further training on now shooting yourself in the foot, crime prevention, and physical restraint techniques. The Civilian Job equivalent would be a police officer.
For a long time I have wanted to join something in the Navy because my Dad told me stories about when he was in the Navy, and it sounded freaking awesome. I have never really left the state of Missouri, so the ability to travel for free appeals to me. Plus, free college sounds pretty radical.
