   The Terrex AV81 8x8 wheeled armored personnel carrier was originally developed in Ireland by Timoney for Singapore Technologies Kinetics. Vehicle underwent initial trials in Ireland and United Kingdom and was shipped to Singapore for evaluation in late 2000. Production commenced in 2006. The Singapore Armed Forces acquired at least 135 Terrex armored personnel carriers.

   The Terrex is one of the latest and most advanced APCs. Vehicle has a modular protection system. All-round protection of the steel armor is against 7.62 mm NATO rounds and artillery shell splinters. The front arc withstands 12.7 mm armor piercing-rounds. Add on ceramic-composite armor plates can be added for a higher level of protection. Maximum level of all-round protection is against 14.5 mm armor-piercing rounds. Vehicle has a double V-shaped hull, which deflects mine blasts. It can withstand up to 12 kg TNT explosion under the hull and the vehicle still keep on moving. Vehicle is fitted with NBC protection system.

   Terrex AV81 in an APC configuration is armed with remotely controlled 40 mm automatic grenade launcher and coaxial 7.62 mm machine gun. Alternatively it can be fitted with remotely-controlled 12.7 mm machine gun. This armored vehicle is also available in various turret-mounted armament configurations, but number of personnel carried is reduced. It is worth mentioning that the Terrex has a modular top deck and its configuration can be changed from anti-tank missile carrier to a 105 mm fire support vehicle.

   This armored vehicle is fitted with a battlefield management system, which provides situational awareness of the battlefield.

   The Terrex APC has a two man crew and carrier up to 12 fully equipped troops. It can carry up to 11 tons of cargo internally, in place of the troops. Occupants enter and leave via hull and roof hatches, while commander and driver have their own roof hatches.

   Vehicle is powered by a Caterpillar C9 turbocharged diesel engine, delivering 400 hp. Engine is mounted at the front of the hull. The Terrex has an exceptional mobility achieved using Timoney independent suspension system. It comes with a central tyre inflation system. Vehicle is amphibious and is propelled on water by two hydrojets.

   The AV81 is also offered as an infantry fighting vehicle, armed with a 20- or 30 mm cannon. This variant is fitted with a two-man turret, has a crew of three, and accommodates 8 troops. Other possible variants include mortar carrier, armored ambulance and recovery vehicle.

   The Terrex can be airlifted by a C-130 Hercules or similar cargo aircraft.




   AV82 Yavuz is a variant of the Terrex AV82 APC, built by the Turkish company Otokar. The Yavuz has a number of changes including hull details and more advanced suspension. This vehicle was proposed to various customers but eventually received no production orders.

   Terrex 2 is a modified version with improved amphibious capabilities. It was tailored to meet requirements for the US Marine Corps for their new amphibious armored personnel carrier program.

   Terrex 3 is a further development of the Terrex 2. It was specially developed to meet Australian Army requirement for an armored reconnaissance vehicle. The Terrex 3 is referred in Australia as the Sentinel 2. It lacks amphibious capability of the previous Terrex 2, but is better protected and carries a much more powerful armament. It is fitted with a turret, armed with a 30 mm cannon. This vehicle is operated by a crew of 2 and can carry 11 dismounts.
