The 2cm Flakvierling 38 was a German anit-aircraft gun in use during World War II. The term Vierling literally translates to "quadruplet" and refers to the four 20 mm gun constituting the design. During the war the Flakvierling was mounted on Panzer IV tanks by replacing it's main cannon and the Kriegsmarine mounted it on top of the U-Boats to provide short-range anti-aircraft defence when it's surfaced. The Flakvierling was also a common fixture on trains.
