Direct proof of use
The United Kingdom transferred Mastiff protected patrol vehicles to Ukraine after Russia's 2022 full-scale invasion. UK government reporting in June 2022 said Ukrainian personnel would be trained to use armored vehicles donated by the UK, including Mastiff, Husky, and Wolfhound.
Ukrainian battlefield use is documented beyond the transfer announcement. Army Recognition, citing ArmyInform, reported in June 2022 that Ukrainian naval infantry units in southern Ukraine were training with donated Mastiff PPVs for operational and tactical missions, while Ukrinform reported in July 2022 that Ukrainian marines showed British Mastiff armored vehicles in action.
Later open-source loss tracking and frontline reporting place Mastiffs in combat conditions. Oryx lists Mastiff Protected Patrol vehicles among visually documented Ukrainian armored-combat-vehicle losses, and BBC reporting from the southern front described British-supplied Mastiff armored vehicles as damaged and destroyed during the 2023 counteroffensive.

Timeline
The public record begins with British transfer announcements in April 2022. Sky News reported Defence Secretary Ben Wallace saying the Ukrainian military would receive Mastiff heavily armored patrol vehicles, and Forces News reported Armed Forces Minister James Heappey confirming about 80 Afghanistan-era protected mobility vehicles for Ukraine, including Mastiff, Wolfhound, and Husky.
By June 2022, UK government reporting described Ukrainian personnel training on UK-donated armored vehicles, including Mastiff. In the same month, Ukrainian marine units were reported training with Mastiff vehicles in southern Ukraine, and in July 2022 Ukrinform reported that Ukrainian marines had shown the vehicles in action.
By 2023, Mastiffs appeared in the attritional record of the war. Oryx's visual-loss list includes destroyed, damaged, abandoned, and captured Mastiff Protected Patrol vehicles, while the BBC described damaged and destroyed British-supplied Mastiffs along the southern front during Ukraine's counteroffensive.

Narrative
In Ukrainian service, the Mastiff appears as a protected mobility vehicle rather than as a tank or infantry fighting vehicle. British and defense-media descriptions consistently frame it as a heavy 6x6 patrol vehicle carrying a two-person crew and eight troops, with machine-gun or grenade-launcher armament options and protection originally designed around the mine and IED threat.
The documented Ukrainian role was troop movement and force protection for units operating in a high-risk ground environment. Army Recognition's June 2022 report described Ukrainian naval infantry learning to use Mastiffs for operational and tactical missions in southern Ukraine, and it quoted Ukrainian officer assessments that emphasized reliability, speed, maneuverability, and protection compared with older Soviet-derived combat vehicles.
The sources do not establish a complete Mastiff fleet history in Ukraine. They do support the core sequence: British transfer and training in 2022, Ukrainian marine use shortly afterward, and later battlefield attrition documented through visual-loss lists and southern-front reporting.
