M551 Sheridan Tank

The M551 Sheridan was an American light tank developed in the 1960s. It was named after General Philip Sheridan, a Union general in the American Civil War. The tank was designed to be air-transportable and to provide direct fire support for airborne troops. It was armed with a 152mm gun-launcher, capable of firing conventional ammunition and the MGM-51 Shillelagh anti-tank missile.

The Sheridan was notable for its service during the Vietnam War, where it was used by the United States Army. Its light weight allowed it to traverse the difficult terrain of Vietnam more easily than heavier tanks. However, its light armor made it vulnerable to enemy fire. Despite its limitations, the Sheridan was appreciated for its mobility and firepower.

After Vietnam, the Sheridan continued to serve in the U.S. military, including in the 1991 Gulf War. It was eventually phased out of active service in the 1990s. Today, the M551 Sheridan is remembered as a unique vehicle that combined the roles of a tank and an anti-tank missile launcher.
