to about 6 km/h. A team of eight horses was needed to tow the gun; another six towed an ammunition box with 42 rounds. Organization and service Red Army The M1910/30 guns were issued to corps artillery. In 1941, three variants of corps artillery regiments existed: Two battalions of 152 mm howitzer-guns M1937 (ML-20) (24 pieces) and one battalion of 107 mm guns (12 pieces). Two battalions of ML-20 (24 pieces) and two battalions of 122 mm guns or 107 mm guns (24 pieces). Three battalions of ML-20 (36 pieces). In September 1941 rifle corps of the RKKA were disbanded, therefore corps level artillery ceased to exist. 107 mm guns were then issued to Reserve of the Main Command units, in 12, 18 or 24-piece gun regiments or 36-piece gun brigades. When corps level was reintroduced in 1943, most 107 mm pieces were again given to corps artillery. New corps artillery regiments had 16-20 pieces and along with 107 mm guns included 122 mm guns and 152 mm howitzers. Many 107 mm guns were also used by the independent artillery regiments of fortified regions and by independent battalions and batteries belonging to fronts and armies. The M1910/30 were used by the Red Army in the Battle of Khalkhin Gol, where four pieces were lost. They also saw action in the Winter War (12 pieces in the 7th Army, 24 in the 467th Artillery Regiment of the 8th Army, 12 in the 51st Artillery Regiment of the 9th Army), apparently without losses. In June 1941, according to different sources, the Red Army possessed 828 (including four belonging to the navy) or 863 pieces of this type. 474 107 mm guns, including a limited numbers of the new M-60, belonged to western military districts. Many were lost at the beginning of the Great Patriotic War. In 1943, the RKKA had at least 490 107 mm guns of all models, the majority of them M1910/30; some remained in service until the end of the war. A surviving piece can be seen in the Artillery Museum in Saint Petersburg. Wehrmacht A number of M1910/30 guns were captured by the Wehrmacht and pressed into service in both field and coastal artillery. In German service, the gun was designated the 10,7 cm K 352(r). In March 1944, the Wehrmacht still possessed 17 pieces, all on the Eastern Front. Summary The modernization of the M1910/30 gave the
