Like other have said already. It is going to be harder now to join the military then the past 10 years. We are drawing down our forces and kicking out people now. Hell the army is suppose to QMP /QSP. 29k. This month alone.
The pentagon did say they wanted to become more of a quick-response Naval and Air power-focused military. I'd suggest Navy or Air Force, just realize the time of them accepting every swingin' dick is at an end. If you have visable tats, you now get compared to all the willing bodies who don't have tats. Record? That's gonna make things more difficult than it is for all the other people who have clean records.
I will tell you, before, they used to beg people to stay in. Now, they have slashed most bonuses and have taken this line of thought- "It's a privilege to be in the military. You're lucky we're letting you stay. You'd better not screw up, and be on top of your game or we're booting you."
Also, realize there is a waiting list for the Air Force at present. I don't know about Navy.
