In summer 1940 the regiment, together with the Regiment "Lancieri di Milano" (7th) and Regiment "Cavalleggeri Guide" (19th), was deployed to Italian occupied Albania for Benito Mussolini's upcoming invasion of Greece. The three regiments formed the Fast Coastal Grouping ("Raggruppamento Celere del Litorale") on the extreme right of the Italian front. On 28 October 1940 the Italian attack commenced, but it quickly devolved into a military disaster. On 10 1940 the Aosta crossed the enemy lines to raid Greek depots at Paramythia, for which the regiment was awarded a War Cross of Military Valour. After its return to Italian lines the regiment spent the rest of the war on the defensive until Nazi Germany's Wehrmacht invaded Yugoslavia and Greece. After the German defeat of Greece the Aosta was on occupation duty in Athens and Piraeus.
