US autonomous ground vehicles deployed in Ukraine combat zones
Forterra deployed over 100 autonomous ground vehicles in Ukrainian combat zones for nine months, where they conducted logistics and casualty evacuation missions. The vehicles demonstrated limitations in autonomous operation, requiring human teleoperation to respond to unexpected enemy threats, and some were lost to enemy fire in difficult terrain.
What happened
Forterra, a U.S. builder of autonomous vehicles, deployed more than 100 of its self-driving ATVs in conflict zones in Ukraine for nine months starting in October 2025, the company revealed on July 7, 2026.
The Lancer vehicles, based on Polaris ATVs and equipped with custom sensors and compute stack, have driven more than 2,500 miles across more than 1,100 missions, carried 777,440 pounds of cargo, and completed 52 casualty evacuations.
Some Lancers have been lost in combat, particularly when stuck in deep mud where Russian forces can target them. Ukrainian soldiers have mainly been teleoperating the vehicles in combat zones because the autonomous systems cannot yet identify unexpected enemy forces and react appropriately.
Reported impact
The vehicles have enabled logistics operations and casualty evacuations for Ukrainian forces who stated the UGVs are critical for maintaining defense. However, losses have occurred and soldiers described the vehicles as too valuable to deploy as freely as drones.
Index analysis
The autonomous systems have not demonstrated capability to identify and respond to unexpected enemy threats without human teleoperators, limiting their autonomy to predefined routes and logistics tasks.
Forterra is working on combining classical robotics algorithms with generative AI to enable more generalised reactions to combat conditions.
Governance controls
The deployment was funded by U.S. defense dollars as part of the effort to support Ukrainian resistance. Ukrainian soldiers' demands focus on cost reduction to enable higher attrition rates, as the current vehicles are too expensive to risk as freely as disposable drones.
