The Class-B Standardized Military Truck or "Liberty Truck" was a heavy-duty truck produced by the United States Army during World War I. It was designed by the Quartermaster Corps with help from the Society of Automotive Engineers in 1910 in an effort to help standardize the immense parts catalogue and multiple types of vehicles then in use by the US military, as well as create a truck which possessed all the best features of heavy truck technology then available. It was the first official standardized motor vehicle adopted and produced by the US Military.
