Direct proof of use
Defender Media reported on 11 November 2025 that Ratel and Tencore would deploy mobile UGV repair teams directly to Ukrainian military units starting in December, citing Ratel founder Taras Ostapchuk. The report describes the workshops as support assets for combat units: they would provide diagnostics, technical repair, software updates, upgrades, and on-site work where the unit was stationed.
Ratel Robotics' own Mobile Workshop product page identifies the exact Ratel support vehicle as a mobile unified workshop for Ratel UGVs. The official page describes a Renault Master-based vehicle for full-cycle field maintenance and repair of ground robotic systems, with autonomous power, technician work areas, a crane, a high-pressure washer, a recovery trailer, and a 5 t winch.

Timeline
Ratel's public background places the company in Ukraine's wartime ground-robotics sector after the full-scale invasion, while its February 2024 ground-drone article described Ukrainian UGVs as a logistics and casualty-evacuation tool at the front. The mobile workshop appeared publicly as part of that support ecosystem in November 2025.
On 6 November 2025, Ratel's product page listed the Mobile Workshop and its field-maintenance equipment. Five days later, Defender Media reported the Ratel and Tencore mobile repair-service plan for combat units, including the statement that service teams would work at unit locations to reduce downtime and return robots to the battlefield with minimal delays.

Narrative
The Ratel Mobile Workshop's conflict role is sustainment rather than direct combat employment. It supports Ukrainian UGV units by moving repair capacity closer to the robots that carry cargo, evacuate wounded personnel, lay mines, launch drones, or perform other battlefield tasks. Business Insider reporting from Ratel's Kyiv-region production and training sites in June 2026 described Ratel's wider UGV output moving from factory floors to soldiers and front-line requests as Ukraine expanded its use of ground robots.
The support package is built around field diagnostics, mechanical and electronics work, software support, autonomous power, and recovery equipment. Ratel lists an 8 kW inverter, 10 kWh battery pack, generator, solar panels, technician workstations, mechanical and welding tools, a crane, a washing system, a 1.3 t trailer, and a 5 t trailer winch. Defender Media's reporting on the Ratel/Tencore service effort describes a similar wartime function: mobile workshops would travel to units, reduce equipment downtime, and return robots to service quickly.
Public sources do not identify a dated unit-level incident in which a Ratel Mobile Workshop repaired a named damaged robot. The available evidence supports a narrower claim: by late 2025, Ratel publicly offered the Mobile Workshop as a field-maintenance system for its UGVs, and Ratel/Tencore mobile repair teams were reported as deploying to Ukrainian combat units during the 2014 Russia-Ukraine War.
