Following a spate of incidents, there has been concern that the unarmoured nature of the Wolf exposes the crews to excessive danger, and they are being supplemented by more heavily armoured vehicles such as the Vector, the Mastiff, and the Jackal.

[1] The Ministry of Defence (MoD) later supplemented the Wolf in theatre with a range of armoured vehicles, including the Snatch and Pinzgauer ATV in some utility and liaison roles, and the Supercat MWMIK.

James Arbuthnot, the then Minister of State for Defence Procurement, testified to the rigorous trials the Land Rover went through prior to being adopted in the British military:[4] "The Land Rover vehicle, known commercially as Defender XD, has been subjected to extensive and rigorous trialling in order to ensure that it can meet the high standards of reliability which are essential for operational military vehicles.

It will bring substantial industrial and employment benefits to Land-Rover, and enhance the vehicle's already excellent prospects in export markets.

There were also unfounded Health and Safety (H&S) concerns about the gases involved in welding a galvanised chassis, due to the fact that supplying correct respiratory protection to welders would negate this problem.

It is worth noting that this 'roll cage' is not mounted to the chassis, merely the rear body tub, and has questionable benefit were the vehicle subjected to being rolled over.

To reduce noise and heat from the transmission in compliance with health and safety rules, a special heavy duty matting system was designed for the Wolf by 'Wright Off-Road'.

The Wolf soft top is made of PVC, and the rear flap is fastened either by zippers and Velcro, or by Dutch lacing down the sides, and elasticated straps to cleats on the tailgate.

Fitted with a 'periscope' snorkel, waterproofed electrical systems and instruments, and prepared with grease and graphite lubricant on practically every moving part, these versions can run with the entire vehicle submerged if needed.

Whilst not officially a 'Wolf', the 130 ambulances (with bodies by Marshall Aerospace) used the same chassis and transmission upgrades, identical drivetrains, and the same Defender-based front bodywork.

A variant of TUM is the Weapons Mount Installation Kit[5] (WMIK, pronounced 'Wimik') for use as reconnaissance and close fire support vehicles.

WMIKs are manufactured jointly by Land Rover and Ricardo plc, and feature a strengthened chassis and are stripped down, fitted with roll cages and weapon mounts.

[9] In late 2006, the MoD announced it was purchasing forty new belt-fed Automatic Lightweight Grenade Launchers (ALGL) made by Heckler and Koch (HK GMG), that can fire up to 360 grenades per minute, with an effective range of 1.5 kilometres (0.93 miles), and a maximum range of up to 2.2 kilometres (1.4 miles); they are to be mounted on WMIKs in Afghanistan.

In the REMUS project, the Ministry of Defence upgraded its Wolf fleet with Front Roll Over Protection System, rear retracting seat belts, Wright off-road front and rear anti vibration acoustic matting, wax injection of chassis / bulkhead, and chassis underseal.

These vehicles were essentially arctic-prepared military models (with 24-volt electrics, convoy lighting, military-spec air intakes, internal insulation, and the standard Wolf chassis and suspension upgrades), combined with expedition gear, such as winches, a roof rack, roof-mounted tent, roll cage, etc.

In 2003, the German government placed an order for a fleet of Land Rover Wolf vehicles for security and law enforcement forces.

Vehicles were supplied as a mixture of 12 and 24 volt FFR variants, their powerplants being either the standard Td5 turbodiesel engine, or some 3 litre BMW units.

The contract was cancelled in late 2004 after the German government opted for one with Mercedes Benz who supplied their G-Class (the military version is also called 'Wolf') in various forms, and a small number of these last batch vehicles were imported and immediately sold-off to the private market.
