SU-122 (Mid Production) w/ Interior Kit

In January 1943, the 1433rd and 1434th self-propelled artillery regiments were sent to the Volkhov Front near Leningrad as part of the 54th Army. On 14 January, they saw combat for the first time in Smierdny region. After that, it was decided SU-122s should follow between 400 m and 600 m behind the attacking tanks; sometimes this distance was shortened to between 200 m and 300 m. The use of SU-76 tank destroyers together with SU-122s proved unsuccessful. Based on combat experience, the organization of self-propelled artillery regiments was changed; the new regimental organization consisted of two batteries of SU-76 tank destroyers and three batteries of SU-122s, for a total of 20 self-propelled guns. In April, the organization of self-propelled artillery regiments was again changed. Separate regiments were created for SU-76 tank destroyers (light self-propelled artillery regiment) and SU-122s (medium self-propelled artillery regiment). The medium self-propelled artillery regiment consisted of four batteries of four SU-122s each. Each regiment was also equipped with either an added SU-122 or a T-34 for the commander and a BA-64 armoured car. This organization remained in place until the start of 1944 when the SU-122 began to be replaced by the SU-152, ISU-122 and ISU-152 heavy self-propelled guns, and the SU-85 tank destroyers.
