The Centurion is significant in the history of British armoured fighting vehicles as well as being one of the most important post-war Western tanks. Introduced into British Army service in December 1946, versions of Centurion were still serving with British forces in the Iraq War of 2003, some 58 years later. Centurions have also seen combat in the Korean and Vietnam Wars, in the Middle East wars, and in the Indo-Pakistan War (1965) where it fought against US-supplied M47 and M48 Patton tanks. The Haynes Centurion Tank Manual is published in association with the Tank Museum and has been written with full access to the museum's Centurion collection.
