The Maultiers were created because it was found that during the first winter in the Soviet Union it became evident that wheeled vehicles were unable to deal with the terrible road conditions. A low cost halftrack was needed to perform a regular truck's duties.
Two ton trucks made by Opel, Ford, and Klöckner-Humboldt-Deutz, and a four ton truck made by Mercedes-Benz were converted.
The rear axle was removed and a track, made from PzKpfw II parts, were added.
The Heer ordered 3,000 conversions to the Nebelwerfer model to be made.
The Maultier was used mostly on the Eastern Front. It didn't perform as well as the regular half-tracks but did well enough for moving supplies.
