In 1980, at the beginning of the war, the Iraqis main efforts focused on capturing of Khuzestan - the main oil-producing region of Iran. They managed to take control of a significant territory in this region, a large port and refinery center Abadan was also besieged. However, the protracted battle for Khorramshahr and Susangerd cities led to the fact that the Iraqis were no longer able to capture the two next major Iranian cities - Dizful and Ahvaz, but only besieged them. Destruction of a major Iraqi group between Ahvaz and Susangerd became the main goal of the first major Iranian counteroffensive named Operation "Nasr" (Victory). The main role in the operation was assigned to the 16 and 92ArmBde units. Also, IRGC and militia units were brought to participate in the operation.

• Two operations - 6 and 5 turns for each side (Iran and Iraq), dedicated to the offensive of the Iranian troops in Khuzestan.
  
• Precisely recreated area at the middle between the rivers Karkheh and Karkheh-Kor, 70 sq. km wide.
