The Terrex Infantry Carrier Vehicle (ICV) is an armoured fighting vehicle (AFV) jointly developed by ST Engineering of Singapore and Ireland's Timoney Technology Ltd. and produced by ST Kinetics (a corporate subsidiary of ST Engineering) for the Singapore Army as well as by Turkish auto-maker Otokar (manufacturing it under a license) as the Yavuz for the Turkish military. The Terrex's mass is approximately 25 to 30 tonnes and the vehicle is built on an 8x8 wheeler chassis with modern military vehicle armour. Multiple-type weapon platforms are supported on the vehicle, including both remote-type weapon systems and overhead weapon stations (OWSs).

The Terrex project started off as a private venture between Singapore Technologies Engineering and Timoney Technology, intended for export sales. The prototype Terrex AV81 armoured fighting vehicle was exhibited for the first time at DSEi 2001. The initial AV-81 design utilised conventional coil-spring shock absorbers but later variants introduced of hydro-pneumatic struts with real-time damping control. An electric-hybrid drive system was also developed.

By mid-2004, one prototype and one pre-production model had been built and both were evaluated throughout Asia and Europe, where the vehicle was offered for a number of emerging wheeled armoured vehicle requirements. This was further influenced by the emerging United States' Interim Brigade Combat Team (IBCT) concept, which called for the need of wheeled armoured fighting vehicles (AFV) as opposed to tracked AFVs.

The Terrex AV-82 was developed in 2005 equipped with a more advanced driveline and hydro-pneumatic suspension system, and a number of changes from the AV81 including a flat underbody instead of a V-shaped hull, and revised rear suspension.

The Singapore Armed Forces will acquire at least 135 Terrex ICVs to replace its V-200 armoured vehicles, with all active Infantry and Guards battalions to begin training to operate from the vehicle in February 2010. The Second Battalion, Singapore Infantry Regiment, recently acquired the Terrex as part of its shift into a motorised infantry battalion. The Indonesian Army has plans to purchase 420 units and has also expressed intent to produce the Terrex locally under license. Turkish automaker Otokar has also joined with ST Kinetics to produce the Terrex AV-82 (renamed Yavuz) for the Turkish Armed Forces.
