Direct proof of use
The Mamba Mk2 entry's Russia-Ukraine War link is the small batch of Alvis 4/Mamba-family armored personnel carriers transferred to Ukraine from former Estonian service in 2022. Defense Express reported on 18 May 2022 that imagery at the Ukrainian border showed seven Alvis 4 APCs, describing them as a British-built version of the South African Mamba that had been used by Estonian forces and then given to Ukraine.
Army Recognition reported on 20 May 2022 that Ukrainian armed forces had received Mamba Mk2 4x4 armored vehicles previously in Estonian Army service. DefenceWeb later identified the captured display vehicle in Moscow as an Alvis 4, explained the Alvis 4 licence-production link to the Mamba family, and wrote that Ukraine's defence ministry had announced receipt of Alvis 4 vehicles in May 2022. Oryx separately lists Ukrainian Alvis 4 "Mamba" losses in its visually documented equipment-loss record.

Timeline
The public trail begins in mid-May 2022, when Defense Express and Army Recognition reported Alvis 4/Mamba-family vehicles moving into Ukrainian service from Estonia. DefenceWeb's later reconstruction says photos from that period showed seven vehicles delivered to Ukraine.
DefenceWeb reported that the first recorded combat losses came in June 2022, when two Alvis 4s were destroyed and another was damaged by artillery, abandoned, and then captured by Russian forces. Oryx's Ukraine-loss list records Alvis 4 "Mamba" vehicles as destroyed, damaged, and captured, giving visual-loss support for battlefield use rather than only transfer.

Battlefield role
The sourced record supports a protected-mobility role for Ukraine, not a heavy direct-fire role. The vehicles were armored personnel carriers in the Mamba/Alvis 4 family, and the available conflict-specific sources document transfer to Ukraine, Ukrainian receipt, and losses under battlefield conditions.
The identity of the Ukrainian vehicles is best handled carefully: some reporting called them Mamba Mk2 or Mamba Mk2 EE vehicles, while DefenceWeb identified the captured example as an Alvis 4 manufactured by Alvis UK under a licence-production relationship with the South African Mamba design. For catalog purposes, this usage page links that Alvis 4/Mamba-family wartime evidence to the Mamba Mk2 family entry while preserving the variant distinction.
