The Italian Army ("Regio Esercito") entered the war with 73 divisions (and one fascist Legion of "Blackshirts"), but only 19 were fully operational for combat in June 1940. Italy during the first years of WWII had only small and medium tanks ("Fiat M13/40" and "Fiat M15/42"), that were no match for the Allies tanks. Only in summer 1943 the Italians developed a heavy tank (the "P40 tank") , but just 5 were ready for combat when Italy signed the armistice. The Italian Army had good antitanks (like the "Semovente 75/18") and reliable armoured cars (like the "AB 41") .
