“…Such changes can involve courses of fire, targetry systems, and training devices. For example, the report by Dyer, Schaefer, Bink, James, Wampler and Dlubac (2010) described the changes over a period of 70 years, from 1940 through 2008, in the course-of-fire used for marksmanship qualification. Other examples of changes to marksmanship training over time include the incorporation of the Engagement Skills Trainer 2000 (EST 2000, a marksmanship simulator) for portions of marksmanship training, moving target exercises for Infantry One Station Unit Training (OSUT), transition to use of night vision goggles and aiming lights for night firing, use of the location of miss and hit (LOMAH) technology on live-fire ranges, and introduction of advanced rifle marksmanship (ARM) in Basic Combat Training (BCT).…”
