ISIS has long used brutal tactics to take control and hold onto territory. Beheadings, burning in oil and various other hideously heinous deaths have befallen to those who cross them and many who haven’t.
As their soldiers flee from Mosul they are witnessing something that is making their blood run cold. For once the ISIS soldiers are seeing their own tactics used against them.
As the Kurdish Peshmerga Humvees roll by they see the ornaments the Kurds are adorning their hoods with. Dead ISIS soldiers are displayed like American hunters display deer that they have killed.
