Britain is part of the general push by western countries to field heavier, mine-protected vehicles, via orders for the Mastiff Cougar variant and its smaller 4×4 Ridgback companion. UK forces are also fielding vehicles like the Land Rover WMIK (Weapons Mounted Installation Kit) that have a very different core concept: firepower and visibility over protection. When deployed in mixed groups with more protected vehicles, and used on open terrain like the plains of southern Afghanistan, ‘the porcupine’ (WMIK) has earned enemy respect and commander requests.
The British sought to build on the WMIK’s strengths, while asking for a vehicle that offered both greater firepower, and better off-road mobility. In response, Supacat’s High Mobility Transporter (HMT) was adapted, then adopted, by the British (“Jackal”) and by Australia’s SAS commandos (“Nary”). Success led to more British orders for Jackal 2 and HMT 600 “Coyote” designs, and now Australian Special Forces are adding the new Extenda vehicle to their fleet.
