A Marine with II Marine Expeditionary Force locates practice targets using binoculars while conducting observation lane training at the Division Combat Skills Center aboard Camp Lejeune, N.C., March 9, 2015, during a designated marksmanship course. Marines use binoculars during observation lane training as part of the designated marksmanship course to aid in finding targets that are at a great distance. Observation lane training aids Marines when they later deploy to combat environments where they may encounter threats at variable distances.
