In Soviet service, the Valentine was used from the Battle of Moscow until the end of the war, mainly in the second line. Although criticised for its low speed and weak gun, the Valentine was liked due to its small size, reliability and good armour protection. Soviet Supreme Command asked for its production until the end of the war. In August 1945, 267th tank regiment (40 Valentine III and IX) of the 59th cavalry division Red Army, together with the 65th T-34-85 43rd tank brigade, passed from Eastern Gobi across the mountains Greater Khingan to Kalgan in China.
