A sniper rifle is a high-powered, precision rifle designed for long-range shooting. It is typically used by military and law enforcement personnel to engage targets from concealed positions or distances greater than 500 meters away. Snipers are trained to use their skills in marksmanship, camouflage, and field craft to achieve maximum effectiveness in combat situations. The term "sniper" comes from the military practice of observing enemy movements (known as "sniping") during battles.
