The stalking exercise taught Marines the importance of going undetected during movement and while firing at a target. The stalking exercise was one of many conducted by Marines attending the Scout Sniper Basic Preparation Course over the course of two weeks during the month of April. (U.S. Marine Corps photo by Sgt.
