M551 SheridanThe M551 Sheridan is a light battle tank developed by the United States. It is named after Civil War General Philip Sheridan.
The M551 Sheridan light tank was one of the first pieces of equipment rushed into Saudi Arabia during Operation Desert Shield. Unlike main battle tanks, the Sheridan can be dropped by parachute, making it an important part of the combat power of the 82d Airborne Division. Most systems have been upgraded and improved since the Sheridan was introduced in the 1960s. For example, the M551A1 has enhanced thermal-imaging and targeting sights. Its gun-launcher fires both conventional munitions and Shillelagh missiles.
