M1 Abrams
main battle tank family
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. Conceived for modern armored ground warfare, it is one of the heaviest tanks in service at nearly 73.6 short tons (66.8 metric tons). It introduced several modern technologies to the United States armored forces, including a multifuel turbine engine, sophisticated Chobham composite armor, a computer fire control system, separate ammunition storage in a blowout compartment, and NBC protection for crew safety. Initial models of the M1 were armed with a 105 mm M68 gun, while later variants feature a license-produced Rheinmetall 120 mm L/44 designated M256.
The M1 Abrams was developed from the failed joint American-West German MBT-70 project that intended to replace the dated M60 tank. There are three main operational Abrams versions: the M1, M1A1, and M1A2, with each new iteration seeing improvements in armament, protection, and electronics.
The Abrams was to be replaced in U.S. Army service by the XM1202 Mounted Combat System, but following the project's cancellation, the Army opted to continue maintaining and operating the M1 series for the foreseeable future by upgrading optics, armor, and firepower.
The M1 Abrams entered service in 1980 and serves as the main battle tank of the United States Army, and formerly of the U.S. Marine Corps (USMC) until the decommissioning of all USMC tank battalions in 2021. The export modification is used by the armed forces of Egypt, Kuwait, Saudi Arabia, Australia, Poland, and Iraq. The Abrams was first used in combat by the U.S. in the Gulf War.

Why this record matters
“M1 Abrams” is worth following because a concise public description often conceals a longer documentary argument. Here, Abrams, main and battle provides the most credible route into that argument.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q173684. The Library of Congress control number is sh85079209. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1980 and 2021.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
