Austin Cappelletti, a scout sniper candidate with Weapons Company, 2nd Battalion, 3rd Marine Regiment, prepares a spotting scope during a pre-scout sniper course at Pu’uloa Range Training Facility aboard Marine Corps Base Hawaii, August 14, 2017. Spotters help the sniper account for wind, elevation, atmospherics and observe the placement of the last shot the shooter fired. The known distance qualification course is designed to enhance the Marines’ capabilities to engage targets at known distances and alternate positions. (U.S. Marine Corps photo by Lance Cpl.
