The 5th Division ('Iron Division') is a military formation of the Iraqi Army. The division is currently deployed in eastern Iraq – predominantly Diyala Governorate. Following the losses suffered by the Iraqi Army during fighting in the ISIL campaign in Northern Iraq, the Iraqi security forces became increasingly reliant on non-state militia units – the Popular Mobilization Forces. As of October 2015, Reuters reported that the 5th Division reported to the PMF chain of command, instead of the official military hierarchy.
