Craig Harrison is a former Corporal of Horse (CoH) in the Blues and Royals, a cavalry regiment of the British Army, who from 2009 to 2017 held the record for the longest confirmed sniper kill in combat, at a range of 2,475 m (2,707 yd). Harrison is most famous for his military service in Afghanistan as a sniper, but he also served in the British army in Iraq and the Balkans.

Reports regarding the longest recorded sniper kills that contain information regarding the shooting distance and the identity of the sniper have been presented to the general public since 1967. Snipers have had a substantial history following the development of long distance weaponry. As weapons, ammunition, and aids to determine ballistic solutions improved, so too did the distance from which a kill could be targeted. In mid-2017 it was reported that an unnamed Canadian special forces operator, based in Iraq, had set a new record of 3,540 m (3,871 yd), beating the record previously held by an Australian sniper at 2,815 m (3,079 yd). In November 2023, the record was once again broken by 58-year old sniper, Viacheslav Kovalskyi of the Security Service of Ukraine, who shot a Russian soldier from a distance of 3,800 m (4,156 yd) during the Russian invasion of Ukraine.
