The Soviet invasion of Manchuria was the last military operation in which Soviet T-26 was used. The Red Army had 1,461 T-26s in the far east on 5 August 1945 (1,272 of these were in operable condition). There were many old tanks (mainly T-26 and BT-7 tanks) in far eastern separate tank brigades; these had remained on the Manchurian border during the entire German-Soviet War. To increase the combat effectiveness of these tank units, 670 new T-34-85 tanks were issued to one battalion of each brigade in summer 1945, leaving the other two battalions with their T-26 or BT-7 light tanks as before. For example, the 1st Far Eastern Front had 11 separate tank brigades (80–85 tanks in each, half T-26 or BT) at that time. There were some number of T-26s in 2 tank divisions and 5 tank brigades of the Transbaikal Front. Such tank units participated in the defeat of the Japanese Kwantung Army in August 1945. T-26s often demonstrated better cross-country ability in the far eastern theater of operation than much heavier T-34-85 and Lend-Lease M4 Sherman medium tanks. Also, the T-26's performance was still sufficient to fight against Japanese armoured vehicles. T-26 tanks participated in the victory over Japan parade in Harbin in September 1945.
