Mastiff PPV (Protected Patrol Vehicle) British version of the Cougar HE.

The British Forces variant will, compared to the original Cougar vehicle, be fitted with large, vertical armor plates which cover the large vision blocks and weapon firing ports. This is in line with British Army doctrine concerning the role of the APC/MICV, specifically that it is to carry troops under protection to the objective and then give firepower support when they have disembarked. The Mastiff will be fitted with a turret sporting either a L7A2 GPMG (General Purpose Machine Gun) - the FN MAG 7.62 x 51 mm, L110A1 Light Machine Gun 5.56 x 45 mm or a L1A1 Heavy Machine Gun .50 inch (12.7 mm) BMG (Browning Machine gun), 40mm automatic grenade launchers, or even a 50mm cannon. One aspect of the British Army's approach to APC/MICV units (which differs to that of the United States) is that ability of the average soldier to fire accurately out of the ports of a moving IFV has been questioned. The large armour plates will also give added side protection from RPGs or IED explosions.
