Russian Artillery

By the 1939 Soviet artillery was being upgraded with the old Tsarist guns being replaced by more modern guns and howitzers. Many of these upgrades were still being done when the German invaded and much of this old equipment was either lost or captured. So by 1943 excellent pieced like the 76.2mm Zis-3 gun, 122mm A-19 howitzer and 152mm D-1 heavy howitzer were in full production.
