Mack Defense will display its M917A3 heavy dump truck (HDT) with an armored cab for the first time in public at the Showcase for Commerce, a business and industry trade show and defense contracting exhibition May 29-31 in Johnstown, Pa.

“We are excited to share Mack Defense’s new M917A3 HDT to this important audience,” said David Hartzell, president of Mack Defense. “The armored cab is just one of several survivability and capability upgrades on the M917A3 HDT.”

The third-generation HDT is scheduled for rollout over the next few years to active U.S. Army and National Guard units currently equipped with older trucks. The M917A3 HDT will go to work immediately on important combat support missions overseas, as well as domestic duty in response to floods, fires and other natural disaster needs. The implementation of the new M917A3 HDT brings critical force modernization to the Army with reduced costs for parts and maintenance to meet the Army's changing mission.

The new armored cab is a key survivability feature that exceeds the Army’s blast requirements, while maintaining all interior features of the commercially available Mack Granite model, on which it is based.
