A designated marksman rifle (DMR) is the weapon used by infantries in the designated marksman (DM) role. Although the “sniper” and the “designated marksman” are distinguished by mission and deployment role, rather than by operational range, the DM’s role generally fills the range gap between a regular infantryman and a sniper. DMRs have been developed with this middle ground in mind. DMRs, unlike sniper rifles, are almost always semi-automatic rifles (semi-automatic rifles are quicker than bolt-action sniper rifles, in terms of rapid fire) and typically have larger magazine capacities (10, 20, or 30 rounds depending on the firearm and operational requirements).
