COMSUBIN (Comando Raggruppamento Subacquei e Incursori "Teseo Tesei"; Divers and Raiders Group Command "Teseo Tesei") is the Italian Navy's special operations unit. Italy was the first nation to use frogmen and human torpedoes. The Royal Italian Navy's Naval Assault Divisions are considered to be the precursor of modern Naval Special Forces. Their record can be traced back to World War I and the operation against the Austrian-Hungarian Battleship Viribus Unitis in Pula Harbour in 1918.
In World War II, famous operations include Suda Bay, Alexandria, Gibraltar, and Malta. Italy's frogman group originated in 1938 as the 1a Flottiglia Mezzi d'Assalto (1st Flotilla Assault Vehicles), which was reformed in 1940 as the Decima Flottiglia MAS (10th Flotilla Assault Vehicles, 10a MAS).
