The M1A1 Abrams entered American service in 1980, since then over 10,000 have been produced. They have participated in combat operations with US Army and Marines, Saudi Arabia and others in the Middle East. The tank is the standard tank of the US Army and has been constantly upgraded over the years. They have also been manufactured in Egypt. There are typically four per platoon and they operate in pairs, like fighter planes.
