The Sd.Kfz.8 Sonderkraftfahrzeug (special motorized vehicle) was a Daimler Benz designed German half-track used during WWII primarily as an artillery prime mover for heavy towed guns and infantry transporter. It was used in every campaign fought by Germany in WWII.
The Sd.Kfz.8 could carry 18,000 pounds and tow 15 tons including the 10.5cm Flak 38, and their flak crews.
This particular Sd.Kfz.8 in the American Heritage Museum is particularly rare. It was captured in North Africa by the British in 1942/43 and subsequently could be seen in the 1967 motion picture “The Dirty Dozen” with actor Lee Marvin at the wheel. Built by Krauss-Maffei, it is the only Sd.Kfz.8 on display in North America.
