Firing the Dragunov Sniper Rifle
The Dragunov sniper rifle is a semi-automatic sniper rifle/designated marksman rifle chambered in 7.62×54mmR and developed in the Soviet Union. The Dragunov was designed as a squad support weapon, since according to Soviet and Soviet-derived military doctrines the long-range engagement ability was lost to ordinary troops when submachine guns and assault rifles (which are optimized for close-range and medium-range, rapid-fire combat) were adopted. For that reason it was originally named Dragunov's Semi-automatic Rifle. Read more at http://en.wikipedia.org/wiki/Dragunov_sniper_rifle
