Direct proof of use
The M1083A1P2 is documented in Ukrainian service during the 2014 Russia-Ukraine War through reporting on an M777 artillery battery and later battlefield-loss reporting. On May 15, 2022, a My Ukraine Is / Militarnyi report on the Ukrainian "Scythians" battery said the battery used an American M1083A1P2 tractor with an armored cab to tow the M777 howitzer and transport ammunition and personnel.
A separate January 18, 2023 Ukraine situation report by The War Zone identified a U.S.-donated Oshkosh FMTV M1083A1P2 cargo truck as destroyed in Ukraine. Together, the reports support a Ukraine-side role centered on artillery mobility, ammunition movement, personnel movement, and tactical cargo support rather than direct weapon employment by the truck itself.

Timeline
The public record places the M1083A1P2 in Ukrainian artillery service by mid-May 2022, shortly after U.S. M777 howitzers began arriving and being used in the Donbas and Kharkiv fighting. The first source-backed appearance in this record is the Scythians battery report dated May 15, 2022.
By January 2023, The War Zone was reporting a battlefield loss of a U.S.-donated M1083A1P2 cargo truck in Ukraine. That loss report does not establish a precise location for the vehicle, but it independently corroborates that the M1083A1P2 type was present as donated Ukrainian equipment in the conflict.

Narrative
In Ukrainian service, the M1083A1P2 appears as a support vehicle tied to Western-supplied towed artillery. The Scythians battery report describes a practical artillery-battery role: towing the M777 and carrying the crew's ammunition and personnel. That role matches the truck's cataloged identity as a 5-ton 6x6 cargo member of the Family of Medium Tactical Vehicles rather than a fighting vehicle or launcher.
The documented use occurred during the artillery-intensive phase after Russia's February 24, 2022 full-scale invasion, when U.S.-supplied M777 howitzers were being pushed into Ukrainian service. A Defense Department report dated May 16, 2022 said many U.S.-supplied M777s were already forward in the fight and were providing long-range indirect fire in the Kharkiv area and elsewhere in the Donbas.
The sources do not support a complete count of M1083A1P2 trucks in Ukrainian service, a full unit distribution, or a comprehensive loss record. The directly supported claims are that at least one Ukrainian M777 battery used an American M1083A1P2 for towing, ammunition transport, and personnel transport, and that a U.S.-donated M1083A1P2 cargo truck was later reported destroyed in Ukraine.
