My husband is thinking about joining the NAVY, he has a couple of jobs in mind any info would be great!?

His top picks are Master of Arms, Operations Specialist, Personnel Specialist, Aviation Machinest & Intelligence Specialist, I know they may be a bit scattered BUT like I said were still in the "inquiring stages." I would also appreciate some info of how my life as a NAVY wife will be (please nothing about cheating, I fully trust my hubby & I would never!) We've been together for 6yrs married 2, hes in his early 30's and im in my mid 20's, no children, and im a small town girl who's never lived any where else never been to any other state then TX (yes very sheltered lol, hence me being a bit scared) ANY INFO ON BOTH SUBJECTS WOULD BE GREAT!
