Also, last I checked, "Outward Bound" and the like don't give you a chance to go to college nearly free while earning a full salary and benefits, as you can do in the military (tuition assistance program, to say nothing of the GI Bill and all the other education programs the military offers).
Couple things to point out about the GI Bill.
* You need to pay into the program ($100 per month when I was in) in order to use it; it's not free.
* About 30% of the people who pay in never use their benefits. I was one of those. I separated from service a whopping two months early, which made me ineligible to use the benefits - or get a refund of what I paid in. This didn't, however, prevent the military from calling me back up for several years of reserve duty afterward. I got screwed on that - my "benefit" consisted of paying a few thousand to fund some other person's college instead of my own.
* Of the remaining 70% who do use the benefits, on average they end up using less than half of the benefits they earned.
A recruiter won't tell you that. They will say "You'll earn XXX amount of tuition money." They won't add "The program will cost you $1200 per year and odds are, you will actually use less than 33¢ of every dollar we promise you."
Reasons for that range from getting injured & discharged early, and as a result being ineligible for benefits; having PTSD issues that prevent you from being able to handle college, having to work full time to support yourself and not being able to handle that and college simultaneously, general nonambition (which might apply here), etc.
