Opel Blitz (German for "lightning") was the name given to various light and middle-weight truck series built by the German Opel automobile manufacturer between 1930 and 1975. To cope with the bad road conditions and the rasputitsa mud seasons on the Eastern Front, a half-tracked Maultier (mule) Sd.Kfz. 3 version was built using tracks and suspension based on the Universal Carrier. Among others, these were used as service vehicles for the Messerschmitt Me 323 military transport aircraft. Designer M Bergman
