Join us as we penetrate the history of the world's most sophisticated tank--the M1 Abrams Main Battle Tank. In the most radical departure in U.S. tank design since WWII, the Supertank combines speed, heavy protective armor, and a fearsome 120mm main gun. In 1991, the new and unproven Abrams tank was deployed in Operation Desert Storm. Using night vision and laser targeting, the M1 Abrams tank destroyed Saddam Hussein's armored Republican Guard, and is again doing desert duty in the War in Iraq.
