I've said it before, the only reason I joined the military is cause I was homeless, so those people do exist. On top of that most people don't sign up cause they actually want to fight, its just a well paying job. America has crazy amounts of military and anti "terrorism" propaganda, most people really don't have any idea of the horrors our military commits. And even if they end up realizing it after they join (I didn't even see any of it till I was about a year in) you can't get out, getting out of a military contract is damn near impossible and if you go AWOL you go to jail for a long time.
