Since World War I, our nation’s soldiers have relied on Mack trucks to provide the transportation and construction infrastructure that is critical to meeting the demands necessary to preserve our freedom.

Mack is proud of its history and support of the military. From the green fields of Europe to the sands of the Middle East, Mack has played a vital role in our military’s successful history. Mack’s famous “Bulldog” nickname was started during WWI by the British Tommys who, when facing daunting terrain, would yell, “Send in the Mack Bulldogs.” Mack continues to answer the call today with reliable trucks that deliver superb performance in even the most severe environments and over the toughest terrain.
