The Milizia Volontaria per la Sicurezza Nazionale (MVSN, "Voluntary Militia for National Security"), commonly called the Blackshirts (Italian: camicie nere, CCNN) or squadristi, was originally the paramilitary wing of the National Fascist Party and, after 1923, an all-volunteer Militia of the Kingdom of Italy. Its members were distinguished by their black uniforms (modelled on those of the Arditi, Italy's elite troops of World War I) and their loyalty to Benito Mussolini, the Duce (leader) of Fascism, to whom they swore an oath. They appear in Medal of Honor: Airborne.
