Take charge of Operation Barbarossa and drive towards Moscow or command the steadfast defenders of the Soviet Union. From the early battles for Leningrad and Sevastopol to the tank clash of Kursk and the bitter urban warfare of Stalingrad, this new Theatre Book for Bolt Action provides wargamers with new scenarios and special rules that give them everything they need to focus their gaming on the Eastern Front.
