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.
Reconnaissance vehicles are designed with several philosophies: scout cars used for passive reconnaissance, with a low profile or small size and are lightly armoured to maximize mobility, relying on speed, stealth and cover to escape detection; armoured reconnaissance used for active reconnaissance, distinct from ordinary scouts in weight and size of weapons and armor, designed not to break away from attacks, but to force their way through towards their objective."
