It's called taking out a loan. I'm pretty sure you'll make more money in the military with a college education and will be able to pay off your student loans. I just don't want you to think that you are nothing and then never go to college and regret it later.
I'm sure its not just as easy as taking out a loan, otherwise why wouldn't everyone who had the smarts to just "take out a loan" and go to college? I haven't looked into it and I'm not particularly concerned about it, but you probably know more about it then I do.
