I just learned that the military is made of murderers and bigots?

You are incorrect and ignorant for using wiki links. Don't you know that anybody can write biased info on those sites. Yes it is true that some non-combatants die yet that only happens when they get in the way or try running in front of the line of fire. **** happens. Plus half of the non-combatants become combatants after picking up AK-47'S from a dead friend or family member and trying to kill you or you're teammate.
