Not so much brainwashing, just getting you ready for what you may see/do. You WILL cry, you WILL want to go home, you WILL miss your family, but if you stick through it, you will come out a true soldier and a better person (possibly, unless you go private pyle on us <_<). And just tell them straight out "no leave me alone!", and if they don't block their number or something. THAT EXACTLY WHAT SOMEONE WHO'S BEEN BRAINWASHED WOULD SAY! I had to do boot camp; only thing it did is made me fit, made me respect authority, made me hate war and the milita.
