and 22 ISU-122s. As part of the 1st Polish Tank Corps (which operated both T-34-76 and T-34-85 tanks), the regiment took part in combat action along the River Nysa, located in southwestern Poland in March 1945. In the early months of 1945, the Polish command began to form another ISU-152 regiment, but with too few vehicles, the newly-formed 13th Polish self-propelled artillery regiment received two ISU-152s and two batteries comprising SU-85s. This regiment took part in the Battle of Berlin between April and May of 1945. Post-WWII, ISU-152s remained in service with the Polish military until the early 1960s. Czechoslovakia As part of the Soviet Union's military assistance to friendly or pro-Soviet countries around the world, a few ISU-152s were transferred to the Czechoslovakian military after World War II, which operated them until the end of 1950s. For several decades it was the heaviest armored vehicle in the Czechoslovak People's Army, which used these to test newly-developed anti-tank obstacles. Romania One captured during World War II. The Romanian Army had received 20 ISU-152s during the 1950s; these were assigned to the artillery units of the 6th, 7th and 57th tank divisions of the Romanian Army. They were known as T-152 in Romanian service. Yugoslavia The Yugoslav Army had only one ISU-152 in its inventory.

As a unique vehicle it was used by the Army's Tank School at Bela Crkva. After it was withdrawn from service, this single Yugoslav ISU-152 ended up as a practice target at the Manjača firing range. China In 1955, the Soviet Army moved out from Dalian in northeastern China, officially ending 10 years of military occupation. All weapons and armaments left behind by the Soviet Union were sold to the Chinese People's Liberation Army, including 67 ISU-152s; 45 were given to the newly-created 1st Mechanized Division of the PLA. Democratic People's Republic of Korea During and after the Korean War, ISU-152s were operated by the Korean People's Army of the DPRK.
