Operation Kheibar

Due to sanctions Iran lacked spare parts for its American and British made equipment.

Iran enjoyed a zealous force of Pasdaran and Basij, which could not be backed up with sufficient amount of artillery, air support and tanks.

Eventually the Iranians swept across the marshes and forced the Iraqis out of the Majnoon islands—a major disaster for Iraq.

Iran followed up with a new offensive where 250,000 Iranian troops emerged from the marshland thrusting West and South in the direction of Al-Qurna and Basra respectively, but with the lack of air support as well as lack of armor and artillery, were very vulnerable to Iraqi armored and mechanized forces which managed to repel this large attack.

At the end of the War, Iraq expelled the Iranians from Majnoon island by using combined-arms tactics coupled with chemical weapon attacks.
