The CSIR was formed in an attempt to provide a somewhat "mobile" unit to fight on a front where mobility was key. Two of the divisions were "truck-moveable" and one was a "fast" division. However, this amounted to more on paper than in reality. The CSIR included an Aviation Command (Commando Aviazione) with a limited number of fighters, bombers, and transport aircraft. This command was part of the Royal Air Force (Regia Aeronautica) and was also known as the "Expeditionary Air Corps in Russia" (Corpo Aereo Spedizione in Russia).
