Expended 300 Win Mag shells are seen on the ground as paratroopers assigned to the 1st Squadron, 40th Cavalry Regiment (Airborne), 4th Infantry Brigade Combat Team (Airborne), 25th Infantry Division, U.S. Army Alaska, hone marksmanship skills with M110 Semi-Automatic Sniper Systems and M2010 Enhanced Sniper Rifles on Statler range at Joint Base Elmendorf-Richardson, Alaska, April 6, 2018. A sniper's main responsibility is to deliver discriminatory, highly accurate rifle fire against enemy targets that cannot be engaged successfully by the regular rifleman due to range, size, location, fleeting nature, or visibility.
