A sniper is a military or paramilitary marksman who engages targets from positions of concealment or at distances exceeding the target's detection capabilities. Snipers generally have specialized training and are equipped with telescopic sights. Modern snipers use high-precision rifles and high-magnification optics. They often also serve as scouts or observers feeding tactical information back to their units or command headquarters.
In addition to long-range and high-grade marksmanship, military snipers are trained in a variety of special operation techniques: detection, stalking, target range estimation methods, camouflage, tracking, bushcraft, field craft, infiltration, special reconnaissance and observation, surveillance and target acquisition.
Etymology The name sniper comes from the verb to snipe, which originated in the 1770s among soldiers in British India in reference to shooting snipes, a wader that was considered an extremely challenging game bird for hunters due to its alertness, camouflaging color and erratic flight behavior. Snipe hunters therefore needed to be stealthy in addition to being good trackers and marksmen. In the 18th century, letters sent home by English officers in India referred to a day's rough shooting as "going sniping", as it took a skilled flintlock sportsman a lot of patience and endurance to wing-shoot a snipe in flight. Accomplishing such a shot was regarded as exceptional. During the late 18th century, the term snipe shooting was simplified to sniping. This evolved to the agent noun sniper, first appearing by the 1820s. The term sniper became commonplace in the First World War.
The older term sharpshooter comes from the calque of German word , in use by British newspapers as early as 1801.In the Edinburgh Advertiser, 23 June 1801, can be found the following quote in a piece about the North British Militia; "This Regiment has several Field Pieces, and two companies of Sharp Shooters, which are very necessary in the modern Stile of War". The word alludes to good marksmanship, itself descendent of the shooting competitions () that took place throughout the year in Munich in the 15th century. Small companies of shooters () from the German states and Swiss cantons would form teams of for such popular competitions, proudly carrying flags depicting a crossbow on one side and a target musket on the other. The earliest known date for the creation of a shooting club formed specifically for the use of firearms comes from Lucerne, Switzerland, where one club has a charter dating from 1466. During the American Civil War, Confederate marksmen equipped with the imported Whitworth rifles were known as the Whitworth Sharpshooters.
Modern warfare
Military doctrine Different countries use different military doctrines regarding snipers in military units, settings, and tactics.
A sniper's primary function in modern warfare is to stay concealed at all times and avoid detection. They provide detailed surveillance from a concealed position, often at long range, and reduce the enemy's combat ability by shooting high-value targets (especially officers and other key personnel). In the process, they cause disruption, pinning down and demoralizing the enemy. Typical sniper missions include managing intelligence information they gather during reconnaissance, target acquisition and impact feedback for air strikes and artillery, assisting employed combat force with accurate fire support and counter-sniper tactics, killing enemy commanders, selecting targets of opportunity, and even destruction of military equipment, which tend to require use of anti-materiel rifles in the larger calibers such as the .50 BMG, like the Barrett M82, McMillan Tac-50, and Denel NTW-20.
Soviet- and Russian-derived military doctrines include squad-level snipers. Snipers have increasingly been demonstrated as useful by US and UK forces in the recent Iraq campaign in a fire support role to cover the movement of infantry, especially in urban areas.
Military snipers from the US, UK and other countries that adopt their military doctrine are typically deployed in two-man sniper teams consisting of a shooter and a spotter. A common practice is for a shooter and a spotter to take turns to avoid eye fatigue. In most recent combat operations occurring in large densely populated towns, such as Fallujah, Iraq, two teams would be deployed together to increase their security and effectiveness in an urban environment. A sniper team would be armed with a long-range weapon and a rapid-firing shorter-ranged weapon in case of close quarter combat.
The German doctrine of largely independent snipers and emphasis on concealment, developed during the Second World War, has been most influential on modern sniper tactics, and is currently used throughout Western militaries (examples are specialized camouflage clothing, concealment in terrain and emphasis on coup d'œil).
Sniper teams
Sniper rifles are classified as crew-served in the United States military. A sniper team (or sniper cell) consists of a combination of at least one primary weapon operator (i.e. the shooter) with other support personnel and force protection elements, such as a spotter or a flanker. Within the Table of Organization and Equipment for both the United States Army and Marine Corps, the shooter does not operate alone, but has a backup shooter trained to fulfill multiple roles in addition to being sniper-qualified in the operation of the main weapon.
The shooter focuses mainly on firing the shot, while the spotter assists in observation of targets, accounts for atmospheric conditions and handles ancillary tasks such as immediate security of their location, communication with other parties (e.g. directing artillery fire and close air support). A flanker is an extra teammate who is tasked to act as a sentry observing areas not immediately visible to the sniper and spotter, assisting with the team's rear security and perimeter defense, and therefore are usually armed with a faster-firing weapon such as an assault rifle, battle rifle or designated marksman rifle. Both the spotter and flanker carry additional ammunition and associated equipment.
The spotter is responsible for detecting, identifying and assigning priority of targets for the shooter, as well as assessing the outcome of the shot. Using a spotting scope and/or a rangefinder, the spotter will predict the external ballistics and read the wind speed using an anemometer or physical indicators like the mirage caused by ground heat. Also, in conjunction with the shooter, the spotter will calculate the distance, shooting angle (slant range), mil-related correction, interference by atmospheric factors and the required leads for moving targets. It is not unusual for the spotter to be equipped with a ballistic table, a notebook or a tablet computer specifically for performing these calculations.
Longest recorded sniper kill
The longest confirmed sniper kill in combat was achieved by an undisclosed member of the Security Service of Ukraine in November 2023, hitting a Russian soldier at a distance of during the Russian invasion of Ukraine.
The previous record holder was a member of the Canadian JTF2 special forces who in June 2017 achieved a hit at a distance of .
In November 2009, Craig Harrison, a Corporal of Horse (CoH) in the Blues and Royals RHG/D of the British Army struck two Taliban machine gunners consecutively south of Musa Qala in Helmand Province in Afghanistan at a range of or 1.54 miles using a L115A3 Long Range Rifle.Smith, Michael (2 May 2010) "Hotshot sniper in one-and-a-half mile double kill". The Sunday Times. The QTU Lapua external ballistics software, using continuous doppler drag coefficient (Cd) data provided by Lapua, predicts that such shots traveling would likely have struck their targets after nearly 6.0 seconds of flight time, having lost 93% of their kinetic energy, retaining of their original velocity, and having dropped or 2.8° from the original bore line. Due to the extreme distances and travel time involved, even a light cross-breeze of would have diverted such shots off target, which would have required compensation.
The calculation assumes a flat-fire scenario (a situation where the shooting and target positions are at equal elevation), using British military custom high-pressure .338 Lapua Magnum cartridges, loaded with 16.2 g (250 gr) Lapua LockBase B408 bullets, fired at 936 m/s (3,071 ft/s) muzzle velocity under the following on-site (average) atmospheric conditions: barometric pressure: at sea-level equivalent or on-site, humidity: 25.9%, and temperature: in the region for November 2009, resulting in an air density ρ = 1.0854 kg/m3 at the elevation of Musa Qala. Harrison mentions in reports that the environmental conditions were perfect for long range shooting, "... no wind, mild weather, clear visibility." In a BBC interview, Harrison reported it took about nine shots for him and his spotter to initially range the target successfully.
Military history Before the development of rifling, firearms were smoothbore and inaccurate over long distance. Barrel rifling was invented at the end of the fifteenth century, but was only employed in large cannons. Over time, rifling, along with other gunnery advances, has increased the performance of modern firearms.
1701–1800
Hunting terminology was quickly adapted to warfare by British soldiers. In a 1772 letter, a soldier described enemies firing very accurately:
At the Battles of Saratoga, Morgan's Riflemen positioned themselves in trees and used early model rifles to target senior British officers. Most notably, Timothy Murphy shot and killed General Simon Fraser of Balnain on 7 October 1777 at a distance of about 400 yards.
In early 1800, Colonel Coote Manningham and Lieutenant-Colonel the Hon. William Stewart of the British Army proposed using what they had learned while leading light infantry to establish a special unit of marksmen. Subsequently raised as the "Experimental Corps of Riflemen", they were armed with the formidable Baker rifle rather than the inaccurate smoothbore muskets used by most troops at that time. Through the combination of a leather wad and tight grooves on the inside of the barrel (rifling), this weapon was far more accurate, though slower to load. On 25 August 1800, three companies, under the command of Stewart, spearheaded an amphibious landing at Ferrol, Spain.
1801–1900 The term, "sharp shooter" was in use in British newspapers as early as 1801. In the Edinburgh Advertiser, 23 June 1801, can be found the following quote in a piece about the North British Militia; "This Regiment has several Field Pieces, and two companies of Sharp Shooters, which are very necessary in the modern Stile of War". The term appears even earlier, around 1781, in Continental Europe, translated from the German Scharfschütze. Scouts in the Ashanti army were made up of professional hunters who used their skill as marksmen to snipe at advancing enemy forces in response to detection by the enemy. They executed this often from a perch high in trees. The Whitworth rifle was arguably the first long-range sniper rifle in the world. A muzzleloader designed by Sir Joseph Whitworth, a prominent British engineer, it used polygonal rifling instead, which meant that the projectile did not have to bite into grooves as was done with conventional rifling. The Whitworth rifle was far more accurate than the Pattern 1853 Enfield, which had shown some weaknesses during the recent Crimean War. At trials in 1857 which tested the accuracy and range of both weapons, Whitworth's design outperformed the Enfield at a rate of about three to one. The Whitworth rifle was capable of hitting the target at a range of 2,000 yards, whereas the Enfield could only manage it at 1,400 yards."Minutes of proceedings of the Institution of Civil Engineers, Volume 19" By Institution of Civil Engineers (Great Britain)
