Supacat, part of SC Group, offer two vehicles based on a modified Discovery 4 platforms.
The Specialist Utility Vehicle 600 (SUV 600) is a production standard Land Rover Discovery 4 that is converted to 6x6 or 6x4 configuration for use in the emergency services and wider utility sectors.
The Light Reconnaissance Vehicle 400 (LRV 400) is an open lightweight 4x4 vehicle of the Land Rover Defender class.
The LRV 400 was developed based on a combination of market research and customer feedback from the 2011-unveiling of a proof-of-concept closed cab variant.
Development of the LRV 400 continues, the latest Mk2 shown publicly for the first time at DSEI 2015 (15–18 September).
The most significant design change for the Mk2 is a switch of the automotive platform to the Land Rover Discovery 4 rather than the off-road racer platform previously offered.

Land Rover offered an armoured version of the Discovery 4, the Sentinel.
Protected to Level B6 (defined in accordance with European Standard EN1063 BR6 (glazing) and EN1522 and certified by QinetiQ), according to Jaguar Land Rover the Discovery 4 Sentinel is almost indistinguishable from the non-armoured Discovery 4.
As a factory supplied product the vehicle comes with a Land Rover three-year or 50,000 miles (80,000 km) warranty, the support of Land Rover's worldwide dealer network and a range of additional after sales packages.
The UK Government ministers are often seen ferried around in Discovery 4 Sentinels.

A great number of Land Rover Discovery II and IV were bought and used by Italian Police and Carabinieri.
The vehicles were configured with reinforced iron grating on mirrors and windshields, fire-extinguishing automatic system and run-flat tires, for crowd and riot control operations.
