Different tank classifications emerged in the interwar period. The tankette was conceived as a mobile, two-man model, mainly intended for reconnaissance. In 1925, Sir John Carden and Vivian Loyd produced the first such design – the Carden Loyd tankette. Tankettes saw use in the Italian Royal Army during the Italian invasion of Ethiopia (1935–1936), the Spanish Civil War (1936–1939), and almost everywhere Italian soldiers fought during World War II. The Imperial Japanese Army used tankettes for jungle warfare.
