This 1925 Model AC "Bulldog" truck is similar to what the company provided to the British and US Armies during WWII.  British troops nick named them "Bulldogs" because of their toughness.  Note that the radiator is located just forward of the firewall and the cooling fan was driven by the flywheel.  Originally the Model AC came with hard rubber tires and was introduced in 1916.  Author's photo from the National Automotive and Truck Museum in Auburn, IN.

This photo from the the Mack Truck Historical Museum shows a World War One Model AC.  The radiator was not placed in the front grill to keep it from being damaged by stones on the road and irate teamsters that still used horses and threw rocks at the trucks.

This Mack NO 7&1/2 ton truck is pulling a 155 mm gun through Brest, France in August of 1944, the task it was designed for.   Photo courtesy of the Mack Truck Historical Museum.

Below are photos of a 1945 Mack NM8D 7594 delivered to the US Army on June 12, 1945 and is undergoing complete restoration at the Mack Truck Museum in Allentown, PA.  This 6-ton 6x6 prime mover was being used as a target at Fort Indiantown Gap in Pennsylvania.  Restoration of the truck is scheduled to be completed in time for a parade in Washington, DC during the summer of 2017.  Photos courtesy of Rudy Lev and added 6-14-2016.

Due to the low production number very few are in museum or owned by private collectors.  This pristine example of  Mack NO is in the Overloon Military Museum in the Netherlands.  Photo courtesy of Zandcee.
