“The Islamic State has released photographs detailing the training of its so-called ‘Third Armored Brigade’ in Iraq’s northern province of Ninewa. The images show the use of American-made Mine Resistant Ambush Protected (MRAP) vehicles, as well as old Soviet armor. In addition to displaying the jihadists training with these vehicles, the fighters are also shown undergoing weapons training with AK-47 assault rifles and rocket-propelled grenades (RPGs).”
