The 1st Corps was a corps of the Iraqi Army, established before the Iran–Iraq War. It was located in the north of Iraq. In 1977–78 British military attaches' reports from Baghdad said the 4th Infantry Division was part of the corps, with divisional headquarters at Mosul and brigades at Mosul (5th), Dohuk (18th), Sinjar (21st), plus two unlocated reserve brigades, the 93rd and 99th. Other divisions of the corps reportedly included the 2nd Division at Kirkuk with five brigades, including two reserve; the 7th Division at Sulaimaniyah with five brigades (all active); and the 8th Division at Erbil with six brigades, including the 91st, 95th, and 98th Reserve Brigades.
