The U.S. military has ordered 103 Mack Defense M917A3 Heavy Dump Trucks (HDTs), as part of its existing contract with Mack Defense.

The additional vehicles are part of the previously announced firm-fixed price $296 million contract over seven years that the Army awarded Mack Defense in 2018, which allows for up to 683 trucks. For this new order, 74 HDTs will be purchased from the presidential budget and 29 are being purchased by the National Guard, according to Mack.

The HDTs play a role in construction and upkeep of infrastructure assets, including airfields, roadways, landing strips, supply facilities, and motor pools.
