"The T-18 light tank (also called MS-1, Russian: малый сопровождения, первый, tr. maliy soprovozhdeniya, perviy, "Small [Vehicle for] Support, First [type/example]") was the first Soviet-designed tank. Produced from 1928 to 1931, it was based on the Renault FT, with the addition of a vertically sprung suspension." -Wikipedia
