AMERICA’S LONGEST WAR: Green Berets Brace for Islamic State Offensive in Afghanistan.

The militants have been probing American and Afghan positions and hiding weapons caches in the ridges overlooking Mohmand Valley, which was controlled by ISIS fighters until allied troops chased them into the Spingar mountains at the end of last year.

That operation allowed civilians who had fled Islamic State to return to their stone-terraced farms. Now many families are reversing course in anticipation of an attempt by insurgents to retake the ground.

“The civilians are leaving the valley,” a U.S. Green Beret told troops who arrived this month to help defend an American outpost in the valley. “So those guys are going to be coming out of the mountains anytime now.”

Godspeed and God bless the Green Berets.
