Flakvierling 38 20mm Antiaircraft Gun

The Flakvierling 38 is a German antiaircraft gun used in World War II. It consists of four 20mm Flak 38s set on a quadruple mounting with collapsing seats, folding handles, and ammunition racks. The mount has a triangular base with a jack at each leg for leveling the gun. The tracker traverses and elevates the mount manually using two handwheels. The gun is fired by a set of two foot pedals--each of which fires two diametrically opposite Flak 38s--and can be operated either automatically of semi-automatically. It was widely used against low-flying Allied aircraft and was often installed in flak towers and other permanent mounts.

I've seen film footage of a Sdkfz7 mounted Flakvierling 38 used against ground targets in Italy. It puts out a lot of rounds quickly.
