As a result of the split nature of the Peshmerga forces, there is no central command center in charge of the entire force, and Peshmerga units instead follow separate military hierarchies depending on political allegiance. Multiple unification and depoliticizing efforts of the Peshmerga have been made since 1992. But so far all deadlines have been missed, reforms have been watered down, and most of the Peshmerga are still under the influence of the KDP and the PUK, who also maintain their separate Peshmerga forces. Following the events of the Iraqi Civil War in 2014, the United States and several Europe nations pressured the PUK and KDP to set up mixed brigades of Peshmerga as a condition for aid and funding. The PUK and KDP united 12 to 14 brigades under the Regional Guard Brigades, which were then placed under the command of the Ministry of Peshmerga Affairs. However, officers continue to report to and take orders from their party leaders who also control the deployment of forces loyal to them and appoint front-line and sector commanders
