In late May 2026, soldiers from the 3rd Brigade, 10th Mountain Division walked out to a motor pool at Fort Polk, Louisiana, and signed for a piece of equipment that no frontline infantry unit had ever received before: a fleet of Hunter WOLF unmanned ground vehicles built by HDT Robotics. The delivery, conducted under the Army’s Ground Optionally Autonomous Transport (GOAT) program, represents what HDT Robotics describes as the first time a robotic logistics platform has been placed directly in the hands of an active combat brigade rather than kept inside a test lab or contractor demonstration. That claim has not been independently confirmed by the Army.
The handoff launched a week-long Operator New Equipment Training (OPNET) event at Fort Polk’s Joint Readiness Training Center, one of the toughest pre-deployment proving grounds in the U.S. military. For seven days, infantrymen ran the Hunter WOLF through the installation’s swamps, dense woodlines, and simulated urban blocks, the same terrain they would face on an actual deployment.
“We finally got to put hands on something the Army has been promising for years,” said one 3rd Brigade noncommissioned officer who participated in the OPNET event but was not authorized to speak on the record. “It is not perfect, but hauling batteries and water on a robot instead of my back changes the math on how far we can move in a day.”
What the Hunter WOLF actually carries
The Hunter WOLF, short for Wheeled Offload Logistics Follower, is not a weapon-toting combat robot. It is closer to an autonomous pack mule: a hybrid-electric, six-wheeled platform designed to haul roughly 1,500 pounds of gear and follow a dismounted squad using GPS waypoints or a “follow-me” autonomy mode.
During the Fort Polk training, HDT configured the vehicles with a specific set of payloads that mirror the heaviest burdens light infantry squads carry today, according to a separate company release detailing the evaluation:
- AN/VRC-158 radios for battlefield communications, eliminating the need for soldiers to hump heavy radio sets on their backs.
- Universal battery chargers capable of topping off the dozens of battery types a modern infantry platoon depends on.
- Water purification equipment that can produce clean drinking water in austere environments, reducing reliance on resupply convoys.
- Casualty evacuation (CASEVAC) litter kits that turn the vehicle into a motorized stretcher bearer.
- A 15-kilowatt power export system large enough to run a small command post, sensor suite, or counter-drone jammer.
Each payload addresses a specific problem that light infantry has struggled with for decades: how to sustain a foot-mobile force far from supply lines without breaking soldiers’ bodies under 100-plus-pound rucksacks.
Why the 10th Mountain Division matters
The Army’s choice of unit is deliberate. The 10th Mountain Division is a light infantry formation, meaning its brigades deploy with fewer armored vehicles and heavier reliance on foot movement than mechanized or Stryker units. Soldiers in the division routinely operate in remote, rugged terrain where wheeled supply trucks cannot follow. A robotic platform that can trail a patrol through mud, forest, and rubble fills a gap that no existing vehicle in the light infantry fleet currently covers.
Fort Polk reinforces the seriousness of the trial. The Joint Readiness Training Center (JRTC) is where brigades go to validate their readiness before overseas rotations. Training there subjects equipment to realistic operational stress: opposing forces, limited sleep cycles, degraded communications, and Louisiana’s punishing heat and humidity. If the Army wanted a gentle debut for its new robots, it would have picked a flat test track at Aberdeen Proving Ground, not the swamps of Leesville Parish.
What the Army has not said yet
Every confirmed detail about the Fort Polk delivery comes from HDT Robotics itself. As of early June 2026, no independent Army press release, Pentagon statement, or third-party after-action report has surfaced to corroborate the timeline, confirm the number of vehicles delivered, or share OPNET results. Military public affairs offices often lag behind contractor announcements, and operational security can limit what units disclose about new equipment. Still, the single-source dynamic means performance claims should be read as the manufacturer’s account, not independently validated findings.
Several important questions remain open:
- Acquisition scale and cost. How many Hunter WOLF units does the Army plan to buy, and at what price per vehicle? HDT’s language describes the Fort Polk activity as “training and evaluation,” suggesting the service has not yet committed to full-rate production. The vehicles could be returned, modified, or replaced after the trial period.
- Soldier feedback. Neither release includes direct quotes from brigade commanders, squad leaders, or operators about how the Hunter WOLF handled Louisiana’s muddy lowlands, how loud it is on patrol, or how steep the learning curve proved for troops encountering it for the first time.
- Interoperability. The AN/VRC-158 radio integration hints at alignment with standard military communications architecture, but whether the vehicle’s autonomy software meshes with the Army’s command-and-control networks, or whether it introduces new cybersecurity risks, has not been publicly addressed.
- Competitive landscape. The GOAT program grew out of the earlier Squad Multipurpose Equipment Transport (SMET) effort, which evaluated multiple platforms. Other contenders in the autonomous logistics space, including General Dynamics’ MUTT and Milrem’s THeMIS, have also conducted military demonstrations. No public side-by-side comparison of reliability, payload capacity, or soldier acceptance rates exists to explain why the Hunter WOLF reached a frontline unit first.
What separates Fort Polk from every previous robot demo
For more than a decade, the U.S. Army has tested robotic ground vehicles in controlled environments, published ambitious roadmaps, and then watched programs stall in the gap between prototype and procurement. The GOAT program was designed to close that gap by putting machines into soldiers’ hands early and letting operational feedback, not lab data, drive acquisition decisions.
The Fort Polk delivery is the most visible evidence yet that the approach is producing tangible results. A light infantry brigade is training with robotic logistics vehicles at one of the Army’s most demanding installations, running real payloads through realistic scenarios. That alone separates this moment from the dozens of scripted vendor demonstrations that have preceded it.
Whether it becomes a turning point depends on what happens next. If the Army publishes its own evaluation data, funds additional units, and begins integrating the Hunter WOLF into deployment rotations, the Fort Polk OPNET will look like the starting gun for a new era of unmanned ground logistics. If the vehicles quietly return to a warehouse and the program stalls in budget negotiations, it will join a long list of promising prototypes that never made it past the trial phase. The soldiers of the 3rd Brigade, 10th Mountain Division are now the first infantrymen in the U.S. military asked to answer that question with mud on the tires instead of slides on a screen.
