The M1 Abrams is a third-generation American main battle tank designed by Chrysler Defense (now General Dynamics Land Systems) and named for General Creighton Abrams. Extensive improvements have been implemented to the latest formerly designated M1A2 System Enhancement Package version 3 or SEPv3 and M1A2 SEPv4, respectively versions such as improved composite armor, better optics, digital systems and ammunition. The Abrams was due to be replaced by the Future Combat Systems XM1202 but due to its cancellation, the U.S. military has opted to continue maintaining and operating the M1 series for the foreseeable future by upgrading with improved optics, armor and firepower. The M1 Abrams entered service in 1980 and currently serves as the main battle tank of the United States Army and formerly the Marine Corps.
Rate Of Fire
The French LeClerc main battle tank has an autoloader that can load 12 rounds a minute, or one every five seconds. That may sound fast, but human loaders are actually faster—skilled U.S. Army tank loaders can load the gun in three seconds, and in the first Gulf War, an M1 Abrams tank destroyed three enemy vehicles in five seconds. During lulls in combat, a four man tank can still have one man outside the tank, keeping watch, while the rest of the crew can still man all the tank’s essential functions.
