| Notes | The 122mm M.30 was designed to replace the old divisional howitzers which were still in use in large numbers. The M.30 was a more modern design which allowed for motorised traction and production started in 1940. It was the best divisional howitzer used by the Soviets in world war two and issued to armoured, infantry, mountain and motorised divisions. |
