Direct proof of use
The Polaris MRZR is documented in Ukrainian service through wartime reporting tied to Ukrainian Special Operations Forces imagery. Defense Express reported on July 17, 2022 that the Special Operations Forces Command of the Ukrainian Armed Forces had published video showing an MRZR ultra-light mobility tactical vehicle and a Sportsman MV850 quad bike made by Polaris, with the vehicles described as received from allies.
The same report identified the shown MRZR as the two-seat MRZR-D2 and described Ukrainian SOF operators using the vehicle with optional litter arrangements for wounded evacuation and with a mounted 7.62 mm machine gun. Army Recognition later reported that Ukrainian special-forces social-media footage posted on April 7, 2024 showed Polaris MRZR 4 light tactical all-terrain vehicles moving on a road in Ukraine.

Timeline
Publicly available direct-use reporting for Ukraine begins in July 2022, during the full-scale phase of the war. Defense Express tied the MRZR appearance to a Ukrainian SOF Command video and described the vehicle as an allied-supplied special-operations mobility platform.
The later April 2024 report adds a second public appearance of the family in Ukrainian special-forces service, this time identifying MRZR 4 vehicles. That source supports continued Ukrainian use, but it does not establish a delivery date, donor country, unit name beyond special forces, or combat outcome.

Documented role
In the 2014 Russia-Ukraine War, the MRZR appears as an unarmored mobility and support vehicle rather than as a protected fighting vehicle. The evidence supports special-operations movement, reconnaissance and sabotage mission suitability, rapid troop or equipment movement, casualty evacuation through litter mounting, and a light mounted-machine-gun configuration.
The record also separates direct Ukrainian use from general vehicle characteristics. Polaris background material supports the family identity as a light tactical all-terrain platform, while the conflict-use sources connect MRZR vehicles specifically to Ukrainian special-forces use in Ukraine.
