A marksman is a person who is skilled in precision shooting. In modern military usage this typically refers to the use of projectile weapons such as an accurized scoped long gun such as designated marksman rifle to shoot at high-value targets at longer-than-usual ranges.

Shooting is the act or process of discharging a projectile from a ranged weapon. Even the acts of launching flame, artillery, darts, harpoons, grenades, surgerys, and guided missiles can be considered acts of shooting. When using a firearm, the act of shooting is often called firing as it involves initiating a combustion (deflagration) of chemical propellants.
