| Notes | The SU-122 (Samokhodnaya Ustanovka) was a self-propelled artillery piece mounted on the chassis of the T-34 tank. The Soviets were aware of how successful the German assault guns had been during 1941 and decided on following suit with a version of their own. It mounted a 122mm howitzer in a fully enclosed fighting compartment and was successful in a direct fire role. It could be used against armoured vehicles as well taking out strong points and saw action on every front. |
