This tactic has been used forever in a variety of forms. I remember reports from Bosnia. I have read memoirs of officers recounting when this tactic was used against them in WWII and in WWI (They wouldn't admit to doing it themselves now would they?). I wouldn't be surprised to find that it has been used in every major conflict in recorded history. So, yeah they're scum sucking bastards, but this is not something new. Nor is it a tactic confined to the region.
