This is the BattleGroup 42 mod for Battlefield 1942. This release concentrates on the BF1942 maps up until Kursk in 1943 and adds the correct vehicles to each map. For the Germans these include the German Panzer II, Panzer III, Bison one-man artillery and Hanomag Flak half-track. For the British these include the Crusader, Matilda and Stuart tanks. For the Russians these include the KV1 heavy tank and a corrected T34-76.
The mod introduces appropriate vehicles as the war progresses and should ideally be played (at least once) in chronological order.
