In actual reply to Arethusa, I say look, If your strapped for cash and are just thinking of joining up for any college benefits, and you have weighed the risk reward factor as good as you can, except nothing less than a non infantry MOS. Study and score high on the ASVAB, except nothing less than an in writing gaurantee of an MOS such as admn, supply, air controller, bulk fuel, something like that. Remember the majority of MOS's are in fact non infantry. That probably wont keep you out of Iraq or Afghanistan but you wont be in a line company fighting. Your survivability is nearly a certainty. Do a 4 year hitch, go reserves if you can (MOS you want may not exist near your location) if not youll be fine. Get out and go to school on the GI bill or whatever they have now (when I joined up we had VEAP). You'll never lose those 4 years, in fact when you get out you'll feel heads and tails above everyone else, and you'll never ever forget your service...something to think about.
Edit: hehe a little drunk (first time drinking in a while) I sort of geared that to say definitely join...thats not what I'm saying. Just saying your options, if you decide to, can be exponentially controlable under the circumstances I said. Remember, get it in writing before you sign, if you sign.
