A marksman, or sharpshooter, is a person who is skilled in precision shooting, using projectile weapons, usually with a rifle but most commonly with a designated marksman rifle or a special application rifle, to shoot at long range targets. In the military, marksmen are sometimes attached to an infantry fireteam or squad where they take accurate long-range shots at valuable targets as needed, thus extending the reach of the fireteam or squad. The main difference between military marksmen and snipers is that marksmen are usually considered an organic part of a fireteam of soldiers, whereas snipers tend to work alone.
