History[ | ]

Class: Light Tank
Developed: 1950-1966
Service: 1967-1996
Vehicles Built: 1662
Operators: USA

The epitome of a modern light tank is the M551 Sheridan. Born from the late 1950s program to replace the 76mm Gun Tank M41 Walker Bulldog, the first prototype was built in 1962 with the production running from 1966 to 1970 and with over 1600 vehicles built. Its purpose was to provide the American military with an air-transportable fire support vehicle that could also perform scout duties.

The Sheridan featured several typical elements for this class of vehicles. It had powerful weaponry – a 152mm gun-launcher. By the time this weapon was introduced, it was capable of knocking out practically every main battle tank it would encounter on the battlefield. Apart from firing standard HE shells, it was also capable of launching Shillelagh missiles. The Sheridan was also very light for a tank (it weighed only 15 tons) and fast with its maximum speed reaching 70 kilometers per hour. Powered by a 300 horsepower Detroit Diesel engine, it was agile and accelerated rather quickly.

In the end however, these qualities could not compensate for its very thin aluminum armor. The Sheridan was used during the Vietnam War and it did achieve certain level of success, but it was extremely vulnerable to RPG hits and mine detonations. On the other hand, it could also get to places where other vehicles would not and was able to provide valuable firepower in the muddy terrain where regular main battle tanks were not available. Its rate of fire was however very low – it could only fire around 2 rounds per minute. Its raw firepower on the other hand was (thanks to high-explosive and flechette rounds) quite high.

Since the end of the Vietnam War, the Sheridan Light Tank participated in two other major conflicts (the Panama invasion and the Gulf War) and survived in the U.S. Army service until 1996 when it was finally phased out, mostly because there was generally nothing better available to replace it with.

This ability improves your vehicle's reload speed, allowing it to fire faster for a short period of time. However, for the duration of this ability, the gun also becomes considerably less accurate and ATGMs become far more difficult to aim.
