The Chieftain was the British Army's Main Battle Tank from 1966 to 1986, providing the backbone of its heavy armour during the Cold War. Incorporating a host of revolutionary design features, Chieftains saw combat in the 1980s during the Iran-Iraq War; Kuwaiti Chieftains fought the Iraqi Army during the invasion of 1990; and British Army specialist engineer Chieftains were used in 1991 during Desert Storm. Author Dick Taylor is a former Chieftain and Challenger tank commander. The Haynes Chieftain Tank Manual is published in association with the Tank Museum.
