If I was a poor kid with no opportunities, ofcourse I would join the Armed Forces.
I would join it ASAP. It gives you good skills and it gets you out of the ghetto, so if you get out of it alive, you can get $$$ for school, good skills in technology and hardware nobody else would give you access to.
Heck, I'm thinking about joining myself

and I'm not poor
The only problem is I don't want to be killing Muslims........if I was sure they send me to go fight Slobodan Milosivec
