“…Several studies have shown performance using a weapon simulator system is predictive of live-fire qualification scores using M4/M16 series weapon systems (Crowley, Hallmark, Shanley & Sollinger, 2014;Hagman, 2000;Schendel & Heller, 1985;Torre, Maxey & Piper, 1987). Additionally Scribner, Wiley & Harper (2007) found a strong relationship between live fire performance and performance using a weapon simulator system. Weapon simulator systems have also been successfully used in a number of research efforts to measure the effect of postural stability on marksmanship performance (Baca & Kornfeind, 2012;Hawkins & Sefton, 2011), as well as the effects of creatine and caffeine supplementation on marksmanship during stress induced training research (Tharion, Shukitt-Hale & Lieberman, 2003;Warber, Tharion & Patton, 2002).…”
