From 1927 to the Ethiopian invasionBy 1918, FIAT and Ansaldo were the only industrial complexes large enough to deal with tank production. The first model produced for the Royal Army (Regia Esercito) was a local derivative of the French Renault FT, called FIAT 3000. These vehicles were ready in 1922, and served well to forge Italian interwar armored tactics. A variant developed in 1930, armed with the Vickers-Termi 37 mm (1.46 in) gun, named FIAT 3000B. Both formed the bulk of the Italian army corp, until new models arrived in 1935. From there on, official designations incorporated “Carro Armato or “CA”, meaning “armored carriage” and an abbreviation composed of the army model designation( L for “Leggera”, M for “Medio”, P for “Pesante”), the weight and the year of first production.
