The 2nd Shock Army (Russian: 2-я Ударная армия), sometimes translated to English as 2nd Assault Army, was a field army of the Soviet Union during the Second World War. This type of formation was created in accordance with prewar doctrine that called for Shock Armies to overcome difficult defensive dispositions in order to create a tactical penetration of sufficient breadth and depth to permit the commitment of mobile formations for deeper exploitation.^[1] However, as the war went on, Shock Armies lost this specific role and reverted, in general, to ordinary frontline formations.
