Iraqi army soldiers with the 72nd Brigade, 15th Division,

Iraqi army soldiers with the 72nd Brigade, 15th Division, roll a tire toward their mine-resistant, ambush-protected vehicle during a training event with U.S. Army advisers at Camp Taji, Iraq, April 2, 2015. The soldiers had to change a tire on their vehicle as the last stage of a team competition designed to test their vehicle skills. The U.S. Army advisers are part of the Combined Joint Task Force to degrade and ultimately defeat the Islamic State of Iraq and the Levant by building the military capacity of Iraqi Security Forces, an effort that has produced more than 5,000 newly trained soldiers, with another 4,700 currently in training.
