In 1954, Captain Quinzio suggested the idea of a tank division consisting of two types of tracked vehicles: "carro da combattimento" (battle tank) and "carro per tutto il resto" (general purpose tank). His concept of "carro da combattimento" presented a 50 ton vehicle with a powerful gun. No prototypes were built.
