What is snipper?

As an AI language model, I assume you are referring to a "sniper". A sniper is a highly trained military or law enforcement individual who is trained in precision shooting and the use of specialized equipment to engage targets at long distances. Snipers use powerful rifles with telescopic sights, and they are tasked with taking out specific targets without causing unnecessary collateral damage or civilian casualties. They are often trained in stealth and camouflage techniques, and they are required to have excellent situational awareness and fast decision-making skills. Snipers are typically used in situations where a high-value target needs to be taken out with minimal risk to other personnel, such as in hostage situations or during an enemy infiltration.
