The American Future Scout and Cavalry System (FSCS) and British Tactical Reconnaissance Armoured Combat Equipment Requirement (TRACER) were a joint U.S.–British reconnaissance vehicle program.

A reconnaissance vehicle, also known as a scout vehicle, is a military vehicle used for forward reconnaissance. Both tracked and wheeled reconnaissance vehicles are in service. In some nations, light tanks such as the M551 Sheridan and AMX-13 have also been used by scout platoons. Their armament ranges from a medium machine gun to a large cannon. Modern examples are often fitted with ATGMs and a wide range of sensors.
