The Leichter Kampfwagen II ("light combat car") or LK II was a German light tank prototype of World War I. A development of the LK I, it incorporated a fixed rear superstructure and was armed with a 37mm Krupp or 57mm Maxim-Nordenfelt gun. Its armor was 8 to 14 mm thick, which increased total weight to 8.75 tons. Power was provided by a Daimler-Benz Model 1910 4-cylinder 55-60 hp gasoline engine, giving a maximum speed of 14 to 18 km/h with range of 65–70 km.
