| Notes | The 152mm M-10 was developed to replace the obsolete M.1909/30 and M.1910/37 howitzers. The new howitzer was to have better elevation and a carriage strong enough for motorised towing. Production was halted after around 1.522 had been produced and the reasons behind this was that the weapon was too heavy and was difficult to produce. Around a thousand were in service mainly as divisional howitzers in 1941 and saw action in the opening phases of Operation Barbarossa in which many were lost. |
