The AFL participated in the campaigns of Tunisia and Italy; during the Italian campaign the AFL was known as the French Expeditionary Corps in Italy ( "en Italie or CEFI)" making a quarter of the troops deployed. The AFL was key in the liberation of Corsica, the first French metropolitan department to be liberated. The troops that landed on D-Day were the 1st Battalion Marine Commando Fusiliers () better known as Commando Kieffer. During the Allied invasion of Provence, on 15 August 1944, the AFL made the majority of the troops landing on French shores, capturing the ports of Toulon and Marseille. One of the AFL's garrison and second-line formations, which later helped man the French occupation zone of Germany, was the 10th Infantry Division.
