Michelle Muller, a tactical air control party program manager for Marine Forces Reserve, plots coordinates on a map during the final exercise of the Air Naval Gunfire Liaison Company primer course at Avon Park Air Force Range in Avon Park, Florida, Aug. 11, 2017. The purpose of taking the students out to participate in a dry-fire exercise was to provide a live training event that would increase training value more so than what the Deployable Virtual Training Environment can provide. The DVTE is a computer system that teaches Marines how to plot coordinates to find a target and destroy it, all through a virtual simulation.
