The Soviet light tank T-26, created as a further development of the English Vickers 6-ton, was a unique combat vehicle. Firstly, it was the most popular Soviet tank of the 1930s (more than 11,000 units were manufactured), on the basis of which a record number of prototypes were created (several dozen). Secondly, this tank was a real workhorse of the Red Army - at Lake Khasan and the Khalkhin Gol River, in Spain and China, the Soviet-Finnish War and the Polish campaign of 1939, in the Great Patriotic War and the war with Japan. The T-26 was delivered to Spain, China and Turkey, and captured samples were in service with the Wehrmacht, Romania, Finland and Hungary. And despite the fact that the T-26 design did not receive further development after 1940, this tank went down in history as a reliable and an unpretentious fighting machine, which with its steel chest stood up to defend our country in the most difficult moments.
