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 massive Soviet tank of the 1930s (more than 11,000 were made), 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 - near Lake Hassan 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. T-26 was supplied to Spain, China and Turkey, and captured samples were in service with the Wehrmacht, Romania, Finland and Hungary. And despite the fact that the design of the T-26 did not receive further development after 1940, this tank went down in history as a reliable and unpretentious combat vehicle, which with its steel chest stood up to defend our country in the most difficult moments.
