An Iraqi Army engineer with the 72nd Brigade, 15th Division moves barbed wire out of the way of his fellow soldiers during a combined-arms training exercise at Camp Taji, Iraq, Sunday, March 22, 2015. Iraq Army engineers cleared simulated improvised explosive devices, mines and other obstacles for Iraqi Army soldiers and tanks during the culminating exercise of a three-week advanced training course with U.S. advisers. There are currently 4,800 Iraqi troops in training at four building partner capacity sites in Iraq, with 3,000 of those troops entering training three weeks ago. (U.S. Army photo by Sgt.
