The British Vickers Mk. E had an unusual fate. In its home country, it never entered service or was produced in significant quantities. However, it became known as one of the best tanks of its time thanks to its production in the USSR under the designation T-26. Soviet tanks saw action in Spain, Finland, and China, and more than 10,000 were produced.
At the start of the Great Patriotic War, they were the most numerous Soviet tanks, though they were already terribly outdated by that time. Nevertheless, despite suffering heavy losses, they fought until the very end.
