The DAF YP-408 is a Dutch 8×6 armoured personnel carrier, with three out of four axles driven by the typical DAF H-drive. It has a 6-litre, 6-cylinder diesel engine with a 5-speed gearbox and a 2-speed transfer case. Prototypes were developed in the late 1950s, with the production of 750 vehicles taking place in the 1960s. The YP-408 entered service in 1964 and remained in use with the Dutch army until 1987. A number of vehicles serving with the Netherlands Army in Suriname were handed to the new Surinamese army when that country became independent in 1975. The Portuguese Air Force received 28 ex-Dutch examples in 1992. These were used by its Polícia Aérea (military police), in the air base security role, until the early 2000s.
