The Battle of 73 Easting was fought on 26 February 1991, during the Gulf War, between Coalition armored forces (US VII Corps and UK 1st Armoured Division) and Iraqi armored forces (Republican Guard and Tawakalna Division). It was named for a UTM north–south coordinate line (an "Easting", measured in kilometers and readable on GPS receivers) that was used as a phase line by Coalition forces to measure their progress through the desert. The battle was later described by Lt. John Mecca, a participant, as "the last great tank battle of the 20th century." This battle took place several hours after another, smaller, tank battle at Al Busayyah. The main U.S. unit in the battle was the 2nd Armored Cavalry Regiment (2nd ACR), a 4,500 man reconnaissance and security element assigned to VII Corps. It consisted of three ground squadrons (1st, 2nd and 3rd), an attack helicopter squadron (4th), and a support squadron. Each ground squadron was made up of three cavalry troops, a tank company, a self-propelled howitzer battery, and a headquarters troop. Each troop comprised 120 soldiers, 12–13 M3 Bradley fighting vehicles and nine M1A1 Abrams main battle tanks.
