The man in blue is part of the Battaglione "Loreto" (800-strong) of the Regia Aeronautica, a special unit set on mid-1942; in principle, its duties were the recovery and the defense of enemy landing grounds/airports seized, mainly in the framework of Operation C3, the planned invasion of Malta. In the intentions, the unit was airborne; as it is well known, the plan for Malta invasion vanished, during the summer of 1942.
In november, 1942 "Loreto and the I Battaglione paracadutisti of the Regia Aeronautica were organized as 1. Reggimento d'assalto "Duca d'Aosta".
The parachutists and Two companies of "Loreto" were sent in Tunisia and the other two companies of "Loreto" were sent in Sicily and from may, 1943,in Sardinia, where they gave personnel for anti-parachutists squads.
The "Loreto" was disbanded just before the Italian Armistice.
Hope this helps
