Hathcock also won the 1966 Wimbledon Cup, which is earned by the winner of the US 1,000-yard high-powered rifle National Championship. Even after being severely burned during an attack on an
Amtrac on which he was riding in his efforts to rescue other Marines, which earned him a Silver Star, and after being diagnosed with
multiple sclerosis, Hathcock continued to serve, shoot and instruct. In Vietnam, Hathcock also completed missions involving a "through the scope" shot which killed an enemy sniper specifically hunting him, and a multiple-day solo stalk and kill of an enemy general.

Rob Furlong, beat Perry's distance with a shot in March 2002. Perry and Furlong were part of a six-man sniper team during 2002's
Operation Anaconda, part of the
War in Afghanistan. Harrison's record was surpassed in 2012 by an unnamed Australian sniper, also during the war in Afghanistan, though this was not widely reported. In June 2017, an unnamed sniper from Canadian special forces unit,

The sniper used a Ukrainian-made, multi-caliber anti-materiel sniper rifle named Volodar Obriyu (
Horizon's Lord). The ammunition used was a newly developed .50 caliber round named 12.7×114 mm HL, which was made by
necking down a 14.5×114 mm case. ==Confirmed kills or greater==
