ISU-152 Self Propelled Gun

The ISU-152 used the same concept as the earlier SU-152 with a large 152mm howitzer mounted on a JS-2 hull instead of a KV-1 hull. The ISU-152 combined three main roles, heavy assault gun , tank destroyer and self propelled howitzer. Its main use was as support to infantry and tanks. It entered service in late 1943.
