After the Battle of Caporetto the Chief of Staff of the Italian Army Luigi Cadorna was finally dismissed and replaced by Armando Diaz. Diaz reorganized the army and ordered the Bersaglieri battalions to be reorganized: the companies on foot were reduced to 150 men in three platoons - two of infantry and one of sappers and combat support troops. At the same, the machine-gun companies were increased to eight machine guns, and the submachine-gun sections increased to three and attached to the companies. Each battalion also received a Stokes mortar section, while each regiment received a flamethrower section and a "reparto cannoncini d'accompagnamento" (loosely translated: small accompaniment cannons unit), with Italian copies of the Austrian 3.7cm Infantry Gun M.15.
