Red Storm, the third Soviet-themed DLC for Order of Battle, covers the battles of the Red Army between 1943 and 1945.

The campaign begins with the fierce tank battle near Prokhorovka during Operation Citadel, the last grand German summer offensive on the Eastern Front in mid-1943. Following the failure of Citadel the Red Army will almost always be on the offensive.

The ultimate goal of this campaign is of course the defeat of the Third Reich in the Battle of Berlin. But Red Storm does not stop there - players can opt for another battle after the fall of Berlin and take their core army to the Far East to defeat Japanese forces in the last major Soviet offensive of World War 2 in Manchuria.
