Longest recorded sniper kills
Reports regarding the longest recorded sniper kill that contain information regarding the shooting distance and the identity of the sniper have been presented to the general public since 1967. Snipers in modern warfare have had a long history since 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.
The modern method of long-distance sniping (1.1-kilometre or 0.7-mile shots) requires intense training and practice. A sniper must have the ability to accurately estimate the various factors that influence a bullet's trajectory and point of impact, such as range to the target, wind direction, wind velocity, air density, elevation, and even the Coriolis effect due to the rotation of the Earth. Mistakes in estimation compound over distance and can cause a shot to only injure, or to miss completely. Any given combination of firearm and ammunition will have an associated value, known as the circular error probable (CEP), defined as the radius of a circle whose boundary is expected to contain the impact points of half of the rounds fired. 
Devices such as laser rangefinders, handheld meteorological measuring equipment, handheld computers, and ballistic-prediction software can contribute to increased accuracy (i.e. reduced CEP).
The science of long-range sniping came to fruition in the Vietnam War. Carlos Hathcock held the record from 1967 to 2002 at 2,286 m (2,500 yd). He recorded 93 official kills before an injury halted his service on the front lines. After returning to the U.S., Hathcock helped to establish a school for training Marine snipers, the Marine Corps Scout Sniper School, at the Marine base at Quantico, Virginia.
Hathcock's record stood for over thirty years until Canadian Master Corporal Arron Perry of Princess Patricia's Canadian Light Infantry beat it. Perry held the title for only a few days as another man in his unit (Corporal Rob Furlong) bested Perry's distance with a 2,430 m (2,657 yd) shot in March 2002. Perry and Furlong were part of a six-man sniper team during 2002's Operation Anaconda, during the War in Afghanistan.
The current record is held by Briton Corporal of Horse (CoH) Craig Harrison, of the UK’s Household Cavalry, who recorded a 2,475 m (2,707 yd) shot (confirmed by GPS) in November 2009, also during the War in Afghanistan, in which he hit two Taliban insurgents consecutively. CoH Harrison killed the two Taliban machine gunners with shots that took the 8.59 mm rounds almost five seconds to hit their targets, which were 914 metres (1,000 yd) beyond the L115A3 sniper rifle’s recommended range. A third shot took out the insurgents' machine gun. The rifle used was made by Accuracy International.
Confirmed kills 1,250 m (1,367 yd) or greater
This list is not exhaustive, as such data is generally not tracked nor managed under any official procedure. For example, the Canadian Forces 2002 sniper team that saw two soldiers (Arron Perry/2,310 m and Rob Furlong/2,430 m) set consecutive new records, also made a number of kills at 1,500 m that are not counted here. The list also shows that, in some cases, an armed force command may choose to withhold the name of the actual sniper, for security reasons. The United Nations Security Forces, such as in the Balkans, also had one American sniper (name withheld) attributed with a 1271 yd shot.

- During the Vietnam War Hathcock had 93 confirmed kills of North Vietnamese Army and Viet-Cong personnel. During the Vietnam War, kills had to be confirmed by an acting third party, who had to be an officer, besides the sniper's spotter. Hathcock himself estimated that he had killed 300 or more enemy personnel during his time in Vietnam.
