The '''FV4030/4 Challenger 1''' is a British [[main battle tank]] (MBT) used by the [[British Army]] from 1983 to 2001, when it was superseded by the [[Challenger 2]]. The majority of the Challenger 1 fleet was subsequently sold to [[Jordan]] where it remained in service with the [[Royal Jordanian Army]] until withdrawals were announced in 2018.<ref name="Foss1">{{cite news |last1=Foss |first1=Christopher |title=Jordan restructures its armoured formations |url=https://janes.com/article/78095/jordan-restructures-its-armoured-formations |work=Jane's Defence Weekly |date=22 February 2018 |archive-url=https://web.archive.org/web/20180222180753/https://janes.com/article/78095/jordan-restructures-its-armoured-formations |archive-date=22 February 2018}}</ref> Known locally as ''Al-Hussein'', these vehicles received various Jordanian modifications before being replaced by French-made [[Leclerc tank]]s from the [[UAE]] and ex-Italian [[Centauro (Tank destroyer)|Centauro]] 8x8 wheeled tank destroyers.
