A Ukrainian unmanned ground vehicle armed with a 12.7mm machine gun held a frontline position for 45 days, in what Ukrainian commanders describe as an illustration of how rapidly battlefield robotics is being integrated into combat operations.

The system, known as the Droid TW 12.7 and produced by the Ukrainian firm DevDroid, was operated by the NC-13 (NC13) strike company within Ukraine’s Third Army Corps, according to a report by The Telegraph. The same report quoted the unit’s commander, Mykola “Makar” Zinkevych, describing the episode as a practical example of how remote systems can take on duties normally assigned to infantry.

According to accounts published by the Third Army Corps, the tracked ground vehicle delivered suppressive fire against Russian assault groups attempting to approach the position, while Ukrainian troops remained behind it. The corps said the robot’s role reduced exposure for personnel and helped maintain the line during repeated attacks.

Details of the routine were also outlined in reporting that cited the unit. The vehicle required servicing and resupply roughly every two days; operators were positioned several kilometres from the frontline and moved forward to conduct maintenance and replenish ammunition before returning to cover. In the same reporting, Zinkevych said the drone enabled the defence of positions that would usually require a small group of soldiers.

Ukrainian military media described the episode as a 1.5-month defensive mission conducted without personnel losses in the immediate defensive position, though independent verification of casualty claims in specific engagements is difficult. Business Insider similarly reported that the unit said it rotated the robot between several positions as needed during the 45-day period, while the location and timing were not fully disclosed for operational reasons.

NC13 was announced in September 2025 as a specialised ground robotic systems unit associated with the Third Assault Brigade, which forms part of the Third Army Corps. Ukrainian officials have framed such units as a response to the demands of high-intensity warfare, where exposure on the forward edge brings sustained risk from artillery, loitering munitions and FPV drones.

Ukrainian Ground Robots Play Key Role in First Drone-Led Capture of Russian Forces

The Droid TW 12.7 itself was approved for use by Ukraine’s armed forces in late 2024 as part of a broader effort to “codify” domestically produced systems for frontline service. Manufacturer statements and reporting describe a platform that can be remotely controlled and may use automated navigation to move along a planned route, though the extent of battlefield autonomy in combat use remains unclear.

The episode has also been discussed against the backdrop of fighting around Kupiansk in Kharkiv region, a rail hub that has been contested repeatedly since 2022. In recent days, The Times reported that Ukrainian forces inflicted heavy losses in the area, citing intelligence shared with the British military and describing a reported 27-to-1 casualty ratio. Separately, Ukrainian outlet UNIAN reported comments by military analyst Pavlo Narozhnyi, founder of the charity Reaktyvna Poshta, who said on Radio NV that Russian logistics difficulties could help explain an estimated 1-to-27 loss ratio in the Kupiansk area.

Ukrainian military briefings in January described Russian groups inside parts of Kupiansk as isolated and short of supplies, with clearance operations continuing. Such claims are contested in a fast-moving battlefield environment; independent assessments, including daily updates by the Institute for the Study of War, continue to track fighting and shifting control lines in the wider Kupiansk direction.

Alongside technology-driven adaptations on the Ukrainian side, reports continue to highlight strains in Russia’s force generation and personnel management. TVP World reported on documents describing widespread complaints within the Russian army, including allegations of troops being sent to the front despite serious medical problems. Separately, Russian-language Telegram channels circulated a video appeal attributed to a serviceman identified as Konstantin Shakhnazarov (born 1962), who claimed he was being pressured to extend his contract despite a back injury; the circumstances and claims have not been independently verified.

The juxtaposition between these strands — robotics intended to reduce exposure at the front, and accounts of manpower stress and contested casualty claims — underlines how the war’s tactical evolution is being driven simultaneously by innovation and attrition.
