The L3 series of armored vehicles primarily served the Italian army during the years leading up to World War II. Classified as "tankettes," they were smaller in size than even "light" tanks, lacked a traversing turret, were armed with only machine guns, and were very light in weight. They were just large enough to hold the engine, transmission, ammunition supply, and a crew of two--driver and commander/gunner. These disadvantages were offset by their speed. They could often reconnoiter forward areas and could support the infantry when mobile machine guns were called for.
