Mastiff has been procured to meet the requirement for a medium protected patrol vehicle. It will be used to transport conventional forces who will conduct patrolling tasks and other duties as military commanders see fit. It has been optimised for this role through a series of modifications, which include additional protection measures and self defence equipment.
The Tempest Mine Protected Vehicle has been configured for use by Explosive Ordnance Disposal (EOD) teams for specialist tasks such as EOD reconnaissance, rescue and recovery and route proving; they have some UK specific EOD modifications.
I am withholding details about specific levels of protection as the information would, or would be likely to, prejudice the capability, effectiveness or security of our armed forces.
