The Carro Veloce L3/33, sometimes known as the CV-33, was armed with a 6.5mm machine gun. The Flamethrower variant, L3 Lf, "Lancia fiamme" (flamethrower) was designed in 1935 and had the machine gun replaced with a flamethrower nozzle. Fuel for the flamethrower was carried in an armoured towed trailer capable of holding 500 litres. The range of the weapon was fairly limited.
