This study evaluated the combined effects of a shooter s anthropometric dimensions, weapon design attributes, firing position, range, and sex on marksmanship. The US Army Research Laboratory M-Range live fire test facility was used to conduct the study. Study participants consisted of a random sample of 26 Army Soldiers recruited from the US Army Research, Development and Engineering Command Solider Support program. The study participants fired the M16A2 rifle, M4 carbine, and the Heckler Koch HK G36 weapons that feature different barrel lengths and weights. Shooters were asked to fire at 50-, 100-, and 150-m targets. The multiple regression analysis indicated a high degree of correlation among the independent variables however, the results also indicated that isometric strength, hand length, and rightward horizontal neck rotation may predict shooting performance under time pressure while firing from either a reflexive firing position or a prone firing position. Shooting performance was measured in terms of hit ratios and the radial error from a designated aimpoint. A multiple regression analysis was performed to develop a mathematical model that expresses shooting performance as a function of associated anthropometric data, weapon design data, firing posture, range and sex.
