There have been articles on FR about gang members, Muslims and whatnot joining the military. Gang graffiti has been seen in Iraq etc.
So some of these scum have had military training courtesy of US taxpayers.
Training IS important. No doubt. Tthis is a fact one would be foolish to ignore.
Nevertheless, “training” can not take the place of unit cohesion and competent leadership: two qualities seldom seen in ad hoc mobs.
