I'm repeating some of the things I said in PM's as well, but adding some more stuffz.
Now is DEFINITELY not the time to join the military. Our country is in some serious economic \"Watch your language\" and there is literally no way we will ever recover from it. It sucks...it's sad...but it's the truth. That said, military spending will be the next major thing on the chopping block (rightfully so) as moderate Americans demand increases in social services (with Occupy Wall Street at the front of the movement). Soldiers across the US are already going without pay and are literally forced to re-enlist in order to not be homeless once they return to civilian life. Of course, with things heating up between Israel/US and Iran/China, the possibility of another war involving the US is growing more likely every day. This is both a good thing and a bad thing, depending on how you look at it. A large war involving the US would reproduce 20th century military-industrial complex spending and could bring us out of the \"Watch your language\"-hole we're in (especially if somehow China got blown up in the process, since they own most of our debt). On the same note, that will mean that if you are enlisted at the time, you will probably go to war and see some of the 21st century's worst bloodshed.
My suggestion? Go to school. Get a degree in something you're interested in (that has applications in civilian and military life), then see how you feel about the military once you've gotten said degree. From there, you can join a branch of your choice under that degree as an Officer...or enter the civilian workforce and refuse to take orders from a corrupt, self-destructive government.
Don't get me wrong, I \"Watch your language\" love America. It's just that there is this little problem we like to call the 1%: the greedy, power-hungry, religiously-motivated, bigoted, misinformed, and otherwise incapable political and economic leaders that are \"Watch your language\"-bent on driving this country into the ground if it means they get to retire to their private island in peace.
