==== United States Army ====
The [[United States Army]] [[101st Airborne Division]] recognized the need for a Squad Designated Marksman when they encountered fires beyond the 300-600m range. In 2004, they began issuing M14s to specially trained soldiers for Designated Marksman work. The [[82nd Airborne Division]] deployed with designated marksmen, trained on the M-4 using ACOGs with great success out to 600m, some 82nd Airborne units were issued M14s. The [[3rd Infantry Division (United States)|3rd Infantry Division]] saw limited use of a modified M16, which was accurized in a manner similar to the U.S. Marines SAM-R, unofficially designated the AMU [[Squad Designated Marksman Rifle]] (SDM-R). This rifle was designed for engagements up to 1000m.

The U.S. Army DM also uses the predecessor of the M16 rifle, the M14, in certain infantry line units. These are commonly equipped with Leupold optics, a Sage stock and are designated the [[Crazy Horse rifle|M14SE Crazy Horse]].<ref name=Kokalis>{{cite journal|first=Peter|last=Kokalis| journal=Shotgun News|title= M14 reborn: Crazy Horse and the Romanian Option| pages=20–22, 24, 26|year=2005|issue=12|volume=50}}</ref>
