<P> 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 in modern warfare 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 British Corporal Craig Harrison at 2,475 m (2,707 yd). </P> <P> Although technology such as electronics have improved, optical equipment such as rangefinders and ballistic calculators have eliminated manual mathematical calculations to determine elevation and windage, the fundamentals of accurate and precise long - range shooting are the same as throughout the history of shooting, and the skill and training of the shooter and his spotter where applicable are the primary factors . Accuracy and precision of ammunition and firearms are also still reliant primarily on human factors and attention to detail in the complex process of producing maximum performance . </P> <P> The modern method of long - distance sniping (shots over 1.1 kilometres or 0.7 miles) 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 speed, 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 . </P>
