^^^^^^^ you would be suprised. it ain't like the streets by any means i assure you. every time you look at em, you will still see a scrapa or whatever, but things are a little different until you are done with the conflict with a foreign country, i assure you. to be in the military, you would have both sworn in to the u.s. military, to have each others back, that's just the way it is. but when shit settles down, you will still think the same of them like you did when you first found out they were from a rival gang. it's like there are quite a few racists and shit that are in the military, and their whole life they were taught to hate blacks and mexicans and shit, not quite on the level of norte/sur, but close. and they still fight for each other like brothers out there. but as soon as the conflict is over, they would still start a fight over calling someone the "n" word or some silly shit. it's like battle on the field isn't real life, but when it's over, real life starts again
as for boot camp, that shit will make you want to be your own closest homeboys ass if they do some shit that will make you have to do more pushups. that's what the job of the drill instructor is.....to throw everything at you inside your head, so of course, you gonna fight someone you already don't like.
