The Carro Armato M13/40 was an Italian World War II tank designed to replace the M11/39 in the Italian Army at the start of World War II. It was the primary tank used by the Italians throughout the war. The design was influenced by the British Vickers 6-Ton and was based on the modified chassis of the earlier M11/39. Production of the M11/39 was cut short in order to get the M13/40 into production. The name refers to "M" for Medio (medium) according to the Italian tank weight standards at the time, 13 tonnes was the scheduled weight and 1940 the initial year of production. Designer M Bergman
