The Dutch only received 5 RG-31s from Canadian Forces in Afghanistan until the arrival of their Bushmasters in October 2006. This is probably a debatable addition.

These are debatable since Canada is reported to have acquired only 5 of each.

Woulfhound is the British name for Force Protection's new Tactical Support Vehicle (TSV), a Cougar variant. The Husky is based on Navistar's MXT family, a losing entry in the M-ATV program. There is some suggestion that the British Army is using a 4x4 Cougar A2 variant, referred to as the Ridgeback, essentially a 4x4 version of the Mastiff. I can't seem to find any concrete info on this quickly and its not the on the MoD website.

The British also contracted with Technical Solutions Group (an entity related to what is now Force Protection) in 2001 for the delivery of 8 mine protected vehicles based on the Lion 4x4, the vehicle from which the Buffalo and Cougar were eventually derived. The Buffalo was derived from the 6x6 Lion II vehicle, while the Cougar was a vastly improved derivative of the original 4x4 vehicle. It is not at all clear what happened to the vehicles. Delivery was apparently complete by February 2003 and there was still mention of the vehicles as of 2006 (referred to only as Mine Protected Vehicles). These vehicles were referred to as Tempest by TSG, Typhoon being the name initially applied to the 6x6 variant that became the basis for the Cougar.
