Pretty sure he already explained this, Military pays for his school, plus he gains experience cooking for his fellow troops. Perhaps more reading & less trolling would do you a little good.
He's joining the army not the fucking Taliban you fuck. It's one thing to shit on Milenko, but shitting on the troops as a whole, is just plain douchey.
Once again pretty sure he covered this, had you actually taken 2 seconds to read the fucking thread & not been so hell bent I'm trying to be a fuckhead & troll the kid (who is finally doing something decent with his life) you would seen the answer to your question already.
Wait... did I just defend Milenko?, holy shit the world really must be coming to an end.
