Italian special forces

The Italian Special Forces include special forces units from several branches of the Italian Armed Forces: the "Esercito Italiano" (Army), the "Marina Militare" (Navy), the "Aeronautica Militare" (Air force) and the "Arma dei Carabinieri" (Gendarmerie).
Italian Armed Forces special units are divided into Special Forces (TIER 1) and Special Operations Forces (TIER 2), and the "Comando operativo interforze delle forze speciali" (Joint Special Forces Operations Headquarters) is responsible for the operations carried out in response to Defense requirements.
Italian Navy special units.
Special Forces.
The Italian Navy special forces unit is the Divers and Raiders Grouping "Teseo Tesei" ("Comando Raggruppamento Subacquei e Incursori Teseo Tesei" - COMSUBIN). Specifically the 250-350 men of the Operational Raiders Group are the special forces section of the elite unit.
COMSUBIN's origins lie with the famous Italian special units "X MAS" (Italian acronym for "Anti Submarine Motorboats"). The name referred to an early vehicle employed by the units, an explosive-laden crewless motorboat ("barchino") which was aimed and launched against enemy submersibles (keep in mind that until well after World War II subs were essentially surface ships with the capability of temporarily diving underwater for attacks). After World War I much study and development went into underwater raid techniques but the unit's name was never altered, leading to the false impression that Italian seafaring commandos were still relegated to anti-submarine warfare only.
Instead many flotillas were armed and equipped to direct raids on enemy ships using explosive head-charges in guided torpedoes with 2-man crews ("Siluri a Lenta Corsa" or S.L.C.), with hand explosive charges (by frogmen) or with small, fast, self-explosive boats (S.M.A.).
Special Operations Forces.
Also the raiders approached the target by means of submarines with special tanks installed on the external bridge containing the special vehicles (S.L.C.).
