The Italian Corpo Aeronautico Militare (Military Aviation Corps) was formed as part of the Regio Esercito (Royal Army) on 7 January 1915, incorporating the Aviators Flights Battalion (airplanes), the Specialists Battalion (airships) and the Ballonists Battalion. Prior to World War I, Italy had pioneered military aviation in the Italo-Turkish War during 1911–1912. Its army also contained one of the world's foremost theorists about the future of military aviation, Giulio Douhet; Douhet also had a practical side, as he was largely responsible for the development of Italy's Caproni bombers starting in 1913. Italy also had the advantage of a delayed entry into World War I, not starting the fight until 24 May 1915, but took no advantage of it so far as aviation was concerned.
