Pros
Tricare, BAH, & Training opportunities (if command approves).
Cons
MOST (not all) Leadership are "yes men." You're a piece of equipment to most leaders. Promotions and awards do not correlate with how well you do your job/work with your team, you just take a test and if you're not as awful as most candidates then you make rank. If you do the bare minimum and keep reenlisting you'll make e-6 in ~8 years. The ones that become a burden to the team can cheat the system and perpetuate the cycle of poor leadership by maintaining a pulse and making rank over time. If you're motivated and self driven you can apply to attend extra training IF you reenlist (or have 2+ years left) and command deems you "non-essential" which could be something as simple as"needing you for PMS." Even if you decide early this is not a career and attempt to further your education for an external career, the command can stop your packages for reimbursement/funding for it. If you're lucky enough to evade all these scenarios but decide to get out for whatever reason then you're essentially dumped out of the command with nothing more than a NAM and money you've saved to make the cross country trip home. Don't count on the Navy for ANYTHING, if you're not signing you're reenlistment papers. If you are already in, document all of your medical issues and find a doctor outside the VA to preform any invasive surgeries because they will do the bare minimum/ try to Med. SEP you.
