Why these snipers are on a different level

Sniper rifles and sniper operators always played a vital role in any war, conflict, and defence.
The modern sniper rifle is a portable shoulder-fired weapon system with a choice between bolt-action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centre-fire cartridge.
Generally, a sniper's primary function in modern warfare is to provide detailed surveillance from a concealed position and, if necessary, to reduce the enemy's combat ability by neutralizing high-value targets (especially officers and other key personnel) and in the process pinning down and demoralizing the enemy.
