Target Stop

In 1990, in preparation for Operation Granby, the UK operation in the First Gulf War, 221 Challenger 1 tanks were deployed to Saudi Arabia. British Challengers destroyed roughly 300 Iraqi tanks without suffering a single loss in combat.[citation needed]
On 26 February 1991, a Challenger 1 under the command of Captain Tim Purbrick of the 17th/21st Lancers attached to the Queen's Royal Irish Hussars, destroyed an Iraqi T-55 tank at a range of 3600 metres, followed soon after by a petrol tanker at a range of 4700 metres using L23A1 APFSDS 'fin' rounds with tungsten–nickel–copper penetrators. That same day, a tank of the Royal Scots Dragoon Guards engaged and destroyed an Iraqi tank at a range of 5100 metres using a L26A1 APFSDS with a depleted uranium penetrator. This is believed to be the distance record for a successful tank-on-tank, direct fire, kinetic round engagement.
