Soviet Light Self-propelled Artillery Regiment
When the Soviet’s were searching for an answer to heavier German armour and guns, they first decided on the 76mm ZIS-3 gun. Powerful enough to penetrate most early German armour, the 76mm became the mainstay of Soviet armour until the arrival of the Tiger and panther. Although, like the T-34, the 76mm gun became inadequate in 1943 in dealing with the newer German medium and heavy armour, it was still quite effective against German anti-tank and machine gun positions.
In this role the SU-76 found a new home. Lightly armoured and
open-topped the SU-76 was very vulnerable to German armour and even
infantry. Placing it with Soviet infantry provided it some protection.
This also allowed mobile support for the infantry in dealing with the
German anti-tank line and in destroying tenacious German machine gun
