In the Mediterranean Theatre during 1940–41, Gladiators saw combat with four Allied air forces: the RAF, Royal Australian Air Force, South African Air Force and Ellinikí Vasilikí Aeroporía (Royal Greek Air Force) squadrons. These achieved some success against the Italian Regia Aeronautica, which was mainly equipped with Fiat CR.32 and Fiat CR.42 biplanes, and against Luftwaffe bombers. The South African ace Marmaduke "Pat" Pattle (who served with the RAF), claimed 15 kills in Gladiators during the North African and Greek Campaigns, making him the highest-scoring RAF biplane ace of the war.
