The Fiat 3000 (Model 21) was first used in action in February 1926 in Libya, and subsequently also saw action against the Ethiopians in the Second Italo-Abyssinian War in 1935. It was not one of the tanks used by the Italians in Spain during the Spanish Civil War, however. With Italy's entry into World War II in June 1940, a limited number of Fiat 3000s still in service with the Italian Army were employed operationally on the Greek-Albanian front. They were also among the last Italian tanks to oppose the Allies, as in July 1943, when the Allies landed in Sicily, two Italian tank companies on the island were still equipped with the 3000. One company was dug in and their vehicles were used as fixed fortifications, while the other company was used in a mobile role to respond to the amphibious landing during the Battle of Gela, with few of the tanks surviving the Allied drive.
