What is the definition of a sniper?

A sniper is a highly trained military or law enforcement marksman who engages targets from a concealed position at long distances. Snipers use specialized rifles and optics to achieve high accuracy, often employing stealth and tactics to remain undetected. Their roles can include reconnaissance, targeting high-value individuals, or providing support to ground troops. The effectiveness of a sniper relies not only on their shooting skills but also on their ability to analyze situations and make strategic decisions.
