Mamba Mk2

Also known as
  • Mamba Mk 2
  • Mamba Mk II
  • Mamba 4x4 APC
  • Mamba Mk2 EE
  • Alvis 4 APC

The Mamba Mk2 is a South African 4x4 mine-resistant armored personnel carrier built around a V-shaped welded steel hull and Unimog-derived driveline. The entry also covers the closely related Alvis 4 license-built strand because Ukraine's documented examples came from former Estonian Alvis 4/Mamba stocks transferred after Russia's 2022 full-scale invasion.

Estonian And Alvis 4 Lineage

The Ukraine evidence is strongest when the Mamba Mk2 EE and Alvis 4 labels are read together. SIPRI records seven Mamba APCs moving from Estonia to Ukraine in 2022; reporting that year described Alvis 4 APCs from former Estonian service reaching Ukraine, while later DefenceWeb coverage identified the Moscow display vehicle as an Alvis 4 connected to the same supply line rather than a fresh South African transfer.

Estonian branch

Army Recognition identifies a small Estonian Mamba Mk2 EE batch and places former Estonian vehicles in Ukrainian service in May 2022.

Alvis branch

Defense Express, Militarnyi, and DefenceWeb describe Alvis 4 as the UK-made or license-built Mamba-family vehicle associated with Estonia's transfer to Ukraine.

Evidence limit

The public record supports transfer, Ukrainian service, and destroyed, damaged, or captured examples; it does not establish a separate Ukrainian procurement program or a new South African delivery.

Variants

The Mk2 name covers the 4x4 Mamba production model; export, licensed, and remanufactured versions used related names for specific operators.

VariantConfigurationDesignation notes
Mamba Mk2 EEEstonian Army version

Army Recognition identifies a small Estonian Mamba Mk2 EE batch; Ukraine transfer reporting often identifies the same visible supply stream as Alvis 4 vehicles formerly used by Estonia.

Alvis 4 APCUK-built Mamba-family APC

Defense Express described the Alvis 4 APC as a UK-made version of the South African Mamba, while DefenceWeb later tied the Ukrainian examples to former Estonian vehicles originally delivered by the United Kingdom.

Mamba Mk3Later upgraded Mamba family model

DefenceWeb records 2006 Project Jury remanufacturing of about 220 Mambas, while Army Recognition notes Mk3 changes from the Mk2 baseline.
