Overland AI Unveils Ibex: A Fully Autonomous Military Vehicle Built on Proven Hardware

Overland AI has taken the wraps off the Ibex, a fully autonomous ground vehicle designed for the U.S. military. Rather than engineering an entirely new platform from the ground up, the company built the Ibex on the chassis, engine and drivetrain of the Polaris MRZR, a light tactical vehicle already in service. That decision reflects a deliberate strategy: give defense buyers autonomy that slots into the fleets and supply chains they already operate, instead of forcing them to adopt an unfamiliar vehicle and a parallel logistics tail.

The U.S. Marine Corps has selected the Ibex for integration into its Marine Air Defense Integrated System, a counter-drone platform. Overland AI describes the arrangement as the first production contract primed by a ground autonomy company for the U.S. military — a milestone that signals growing institutional appetite for driverless ground systems.

On paper, the Ibex is capable of carrying 2,000 pounds (907 kg) while autonomously exceeding 35 mph. It can cover roughly 250 miles (402 km) on a single tank at 20 mph, burning either diesel or JP-8, the military-grade fuel already used across U.S. operations. Because it shares components and fuel with the MRZR, units can sustain the vehicle through existing supply chains, and its dimensions allow it to be transported inside a V-22 Osprey. The platform requires no remote control or teleoperation; instead it leans on Overland AI’s OverDrive software to navigate difficult terrain even when communications are degraded.

The Ibex also carries 5 kW of export power, which hints at a broader role than pure transport. Overland AI is pitching each vehicle as a power, communications and computing node positioned at the front line — a mobile hub that could support sensors, radios or other electronics in austere environments. That vision aligns with the company’s existing track record: its autonomy stack has already backed resupply, counter-drone, breaching and electronic warfare missions with the Army, Marine Corps and Special Operations Command.

Greg Okopal, Co-founder and Chief Operating Officer of Overland AI, framed the platform as one shaped by the people who will actually use it. He noted that building Ibex on the MRZR’s proven chassis, engine and drivetrain means it can be fielded on day one and kept running with the parts and fuel units already have on hand.

For the defense autonomy sector, the Ibex launch underscores a practical shift. Instead of chasing maximum novelty, vendors are increasingly tailoring autonomous systems to the logistics realities of the forces they serve — an approach that could speed adoption well beyond this single platform.
