M1 Abrams Main Battle Tank (Army and Marine Corps)

The M1 Abrams Main Battle Tank (heavy tank) entered U.S. service in 1980, a lighter and more versitile tank that emerged from the cancelled MBT-70 and XM803 tank programs. With a series of variants and technology upgrade packages, the M1 Abrams continued to serve the U.S. and allied countries well into the 21st Century.
