No matter where you try to hide, Army Special Forces will find you.
That message is clear by watching this video. Special Forces soldiers catch up with some insurgents in what looks like the only structure in the middle of nowhere. Seriously, it's like finding Luke Skywalker's house on Tattooine.
However, Skywalker didn't have SF hunting him down. The door opens and all hell breaks loose. ISIS should know that, especially since they just freed 70 hostages from their clutches.
