| Notes | The Soviets soon found that the 122mm A-19 had real issues with its carriage and these problems were solved by mounting the 122mm A-19 barrel on the carriage of the new 152mm M.1937 gun/howitzer. These weapons were issued alongside the surviving 122mm A-19s and served in corps artillery regiments. It was issued to corps artillery regiments and saw action against the Japanese and Finns, and served right through world war two. |
