MFS, along with YPG forces, participated in an offensive along the Syria-Iraq border. The joint forces managed to drive out Islamic State forces after the jihadist group took control of Mosul and most of Nineveh Governorate during the Northern Iraq offensive. The operation led to the full control of Til-Koçar, on the Syrian side of the border, and Rabia, in the Iraqi side of the border.[21][22]
