M1 abrams
The M1 Abrams is a third-generation main battle tank produced in the United States. It is named after General Creighton Abrams, former Army Chief of Staff and Commander of US military forces in Vietnam from 1968 to 1972. Highly mobile, designed for modern armored ground warfare, the M1 is well armed and heavily armored. Notable features include the use of a powerful gas turbine engine, the adoption of sophisticated composite armor, and separate ammunition storage in a blow-out compartment for crew safety. Weighing nearly 68 short tons, it is one of the heaviest main battle tanks in service. The M1 Abrams entered U.S. service in 1980, replacing the M60 tank. It served for over a decade alongside the improved M60A3, which had entered service in 1978. The M1 remains the principal main battle tank of the United States Army and Marine Corps, and the armies of Egypt, Kuwait, Saudi Arabia, Australia, and Iraq. Three main versions of the M1 Abrams have been deployed, the M1, M1A1, and M1A2, incorporating improved armament, protection and electronics. These improvements, as well as periodic upgrades to older tanks, have allowed this long-serving vehicle to remain in front-line service. The M1A3 is currently under development.
T-90A
The T-90 is a Russian third-generation main battle tank that is a modernisation of the T-72 (it was originally to be called the T-72BU, later renamed to T-90). It is currently the most modern tank in service with the Russian Ground Forces and Naval Infantry. Although a development of the T-72, the T-90 uses a 125mm 2A46 smoothbore tank gun, 1G46 gunner sights, a new engine, and thermal sights. Standard protective measures include a blend of steel, composite armour, and Kontakt-5 explosive-reactive armor, laser warning receivers, Nakidka camouflage and the Shtora infrared ATGM jamming system. The EMT-7 electromagnetic pulse (EMP) creator is used in testing but not fitted to T-90s in active service. It is designed and built by Uralvagonzavod, in Nizhny Tagil, Russia. From 2011, the Russian armed forces have ceased ordering the T-90, and are instead waiting for the development of the Universal Combat Platform T-99 that is expected to enter service in 2020.
