Soldiers may soon be doing a bit less pack hauling as the US Department of Defense taps American Rheinmetall and Harbinger to develop a new generation of stealthy, inexpensive, and expendable robotic trucks designed to carry cargo to the battlefield. We live in a time of tremendous technological change, to the point where it's easy to think the human condition is on the verge of being transformed. However, spending a few days with an infantry unit can quickly dispel that notion, as soldiers continue to do what they have always done: haul supplies across broken, muddy terrain through sheer muscle power. Today's armies are logistical marvels, with each combat platoon representing the sharp tip of a very long supply spear. Despite militaries operating support networks that rival commercial systems in scale and often exceed them in speed, there inevitably comes a point where all the ships, aircraft, helicopters, trucks, and railways in the world must give way to soldiers manually carrying boxes and bales to the front line. In the hope of narrowing this gap and leaving soldiers better rested, military planners are increasingly turning to robotics. Self-driving trucks have existed for more than 20 years, though their use has largely been limited to convoys overseen by small human crews. The goal now is to create a new family of cargo vehicles capable of carrying materiel while operating within the demands of modern warfare. The new family of vehicles is being developed under a modernization contract, with American Rheinmetall responsible for combat vehicle integration, modular architecture, adaptable mission-kit interfaces, and mission systems engineering. Harbinger will provide its commercially derived drive-by-wire hybrid-electric vehicle chassis and advanced electrification technologies. The aim of the project is to rapidly develop mass-producible, affordable, and attritable robotic platforms for combat, logistics, and sustainment operations. Initial efforts
