I don't know what other frame of reference there really is to use except if it works for A it should work for B. What you get out of your service depends largely on yourself. Some people at boot camp will be high school dropouts and have very little motivation. Some will be redneck hillbillies who will take any chance they get to brag about how great it is to be an American, God's selected people. Some will be much like you and these are the people who you will suffer through a whole lot with. I was fortunate enough not to lose anyone who I was close with. Maybe that brings some bias into my view. I did get shot (the Kevlar saved my life but it hurt like hell), however, and that was scary. Sure I have nightmares sometimes but I don't think it's more often than the average person.
Anyway, we're getting off topic here. I just wanted to throw the GI-bill possibility out there because the poster doesn't come from money. I didn't join up with the idea to have college paid for me either, but it's a really positive thing. If you're lucky you might get stationed in Germany or Japan or something like that and never even see active combat and still get the GI-bill. I think it's for less $ but it gets you through the whole thing.

It might not come up in an interview depending on where you work but I'm positive it makes your resume stick out from the mass. If I were an employer I would certainly be impressed if somebody completed ranger school. Knowing the torture that we went through there it shows the right attitude in a person - never give up.
Rangers lead the way!
