Green Berets assisting the Kurds in Syria are wearing Kurdish militia insignia on their uniforms:

Photos have emerged of American special operations troops in Syria wearing uniform insignia affiliated with a Kurdish rebel group known as the YPG, whose connection to Turkish terrorists could could fuel tension between the U.S. and a key ally in the Islamic State fight.

The images were taken in a village about 40 miles north of the Islamic State group’s self-declared capital of Raqqa, which is the target of a newly announced offensive being led by a disparate group of Kurdish and Arab fighters, and backed by American military advisers and air support. They highlight the complicated network of alliances the U.S. is trying to forge in Syria, and the ethnic and sectarian tensions that could tear apart this fragile coalition.

Speaking Thursday, a top Pentagon official said it’s fairly common for Green Berets and other operators to wear allies’ patches.

This has got to be putting some kinks in Erdogan’s mustache.
