Sniper in the context of "Weapon system"

Demoralization is, in a context of warfare, national security, and law enforcement, a process in psychological warfare with the objective to erode morale among enemy combatants and/or noncombatants. That can encourage them to retreat, surrender, or defect rather than defeating them in combat.

Demoralization methods are military tactics such as hit-and-run attacks, snipers, disturbing the enemy with less-lethal weapons and incapacitating agents, and intimidation such as display of force concentration. Some methods on the strategic scale are commerce raiding, strategic bombing, static operations such as sieges and naval blockades, and propaganda.

A sniper rifle is a high-precision, long-range rifle. Requirements include high accuracy, reliability, mobility, concealment, and optics, for anti-personnel, anti-materiel and surveillance uses by military snipers. The modern sniper rifle is a portable shoulder-fired rifle with either a bolt action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge.

Counter-sniper tactics are military tactics and countermeasures used to avoid, neutralize, or reduce the effectiveness of hostile snipers.

Mouse-holing is a tactic used in urban warfare in which soldiers create access to adjoining rooms or buildings by blasting or tunneling through a wall. The tactic is used to avoid open streets since advancing infantry, caught in enfilade, are easily targeted by machine-gun and sniper fire. Another purpose is to reach enemy troops hidden within a structure.

Long range shooting is a collective term for shooting disciplines where the distance to the target is significant enough that the shooter has to put effort into calculating various ballistic factors, especially in regards to the deviating effects of gravity and wind. While shooting at shorter ranges, a shooter only has to slightly adjust the sights to compensate for limited bullet drop at most, but when the range is extended, wind drift will be the first factor affecting precision to the extent that it must be taken into serious account. Some would argue that long range shooting starts where assessment of wind, distance and various atmospheric conditions are equally important for the results as pure shooting skills - meaning that even if one conducts a technically perfect shot, the shooter will miss the target because of incorrect calculations, neglecting to take some elements into consideration, or merely due to unpredictable downrange conditions. It is widely accepted within interdisciplinary circles that for a standard rifle firing full-powered cartridges (e.g. .308 Winchester), "long range" means the target is more than 600 m (660 yd) away,, while "extreme long range" is generally accepted as when the target distance is more than 1,000 m (1,100 yd) away from the shooter.

There are several competitive match circuits that typically consist of targets at long range. Benchrest shooting events are often between 100 and 900 meters (≈ 100 to ≈ 1000 yards), F-Class is typically the same with 300 to 900 meters (≈ 300 to ≈ 1000 yards). A growing form of interdisciplinary shooting, becoming known as Practical Precision, places targets at virtually any distance from 100 to 1800 meters and the scoring is hit/ miss on steel targets of various sizes and from various positions (standing, kneeling, prone). This type of match is quickly becoming more popular than F-Class.
