The Land Rover Wolf is a light military vehicle manufactured by Land Rover in the United Kingdom (UK), based on the Land Rover Defender, introduced in 1994. The Ministry of Defence (MoD) designates the Wolf 90 (short wheelbase) as Truck Utility Light (TUL) HS, and the Wolf 110 (long wheelbase) as Truck Utility Medium (TUM) HS, where HS stands for 'High Specification'. Land Rover calls it eXtra Duty (XD). The 1992 Snatch Land Rover, fitted with composite armour for ballistic protection, does not use the same 'heavy duty' chassis.
