As time went on, disputes over the leadership and course of the Sadrist Movement continued, with a number of factions breaking off.[3] After returning to Iraq, Sa'ad Sawar consequently managed to rally a substantial number of dissatisfied Sadrists to his cause,[5] and announced the foundation of "Jaysh al-Mu'ammal" in June 2016.[3] The new group reportedly received substantial aid from Nouri al-Maliki, the former Prime Minister of Iraq and a rival to Muqtada al-Sadr,[3] who provided Jaysh al-Mu'ammal with 3 million United States dollar in cash, weapons worth $1,5 million, and the support from a number of tribal sheikhs in central and southern Iraq.[5] Sa'ad Sawar also received support from Iran and other splinter faction of the Sadrist Movements as well, such as Asa'ib Ahl al-Haq.[3]
Led by Sa'ad Sawar, Jaysh al-Mu'ammal is headquartered in Sadr City, Baghdad,[3] where it also recruits most of its forces.[4] A number of pro-Nouri al-Maliki elements in central and southern Iraq have also joined the group or at least provide support.[5]
Unlike Muqtada al-Sadr, who is focused on Iraq, Sa'ad Sawar has emphasized his readiness to provide military support to Shia groups outside of his home country. His group consequently operates in both Iraq as well as Syria, and has also declared its willingness to support the Houthis in the Yemeni Civil War, and to fight with the Bahraini opposition against the SunniHouse of Khalifa.[3]
