Dubbed the "Swiss Army Knife of Combat Vehicles," the Sheridan is an American light tank developed during the Cold War. It was unique in its versatility, combining the capabilities of a tank, a reconnaissance vehicle, and an anti-tank missile carrier. Armed with the MGM-51 Shillelagh anti-tank guided missile and a conventional 152mm gun-launcher, the Sheridan could switch between conventional rounds and Shillelagh missiles rapidly, allowing it to engage a wide variety of targets. Despite its impressive firepower, the Sheridan suffered from mechanical problems and high operating costs, leading to its retirement in 1997. Today, it remains a testament to the ingenuity and ambition of American military engineers.
