Generally speaking, our soldiers do not have the luxury of identifying every threat they come across in the battle zones. Therefore if someones children or anyone for that matter are posing a threat you take them out. My grandfathers best friend was killed in nam by a child that handed him a fruit basket filled with grenades. not only did it kill him but it killed the child too. Therefore I do not blame the child but his parents knew damn well what was going to happen to him. AGAIN, do not blame our soldiers!
Your anecdotes mean nothing compared to their internet charts!
