The 13.2 mm Breda Model 31 was a widely used Italian heavy machine gun produced by Società Italiana Ernesto Breda and used by the Italian Navy and Italian Army during World War II. At sea it was employed as a light anti-aircraft gun, while on land it was mounted on armored command vehicles where it was used as a heavy machine gun. After World War II it remained in use aboard the patrol boats of the Guardia di Finanza.
