The Rheinmetall LandSysteme Light Infantry Vehicle for Special Operations, or LIV (SO), is a german light armoured utility vehicle developed from the Mercedes-Benz G-Class. It is also known by the names Serval, Wolf and AGF. As the name implies, the LIV (SO) is designed specifically for use by special operations forces, and has light armour, high mobility and high firepower. Development of the vehicle started in 2002, and 21 were procured by the German Army for the KSK special forces in 2004. An unspecified number of vehicles were delivered to the Swiss army in 2007.
