The Sd.Kfz. 7 was a half-track military vehicle used by the German Army, Luftwaffe and Waffen-SS during the Second World War. Sd.Kfz. is an abbreviation of the German word Sonderkraftfahrzeug, "special purpose vehicle". A longer designation is mittlerer Zugkraftwagen 8t, Sd.Kfz. 7, "medium towing motor vehicle 8t".
The 3.7 cm Flak 43 was a light anti-aircraft (AA) gun used by Nazi Germany during World War II. It was derived from the 3.7-centimeter (1.5 in) Flak 18/36/37 series of AA guns. It was provided with single- and twin-gun mounts, the latter being designated as the 3.7 cm Flak 43 Zwilling and was in service from 1944 to 1945. In addition to versions used by the Kriegsmarine (German Navy), it served as the main armament of the Ostwind and Möbelwagen and was proposed for use in the Flakpanzer Coelian self-propelled AA guns.
