USAREIM TN-01-2 Statistical Measure of Marksmanship

Washington: Department of the Army, 2001. — 27 p.Training in rifle marksmanship is required of all soldiers upon entrance into the U.S. Army. Subsequent demonstration of marksmanship proficiency on an annual basis is also required. This report describes statistical procedures for the measurement of both rifle marksmanship accuracy (the proximity of an array of shots to the center of mass of a target) and marksmanship precision (the dispersion of an array of shots around their own center of impact) often referred to as "shot group tightness." The statistics presented here are intended for use in the field (with live fire) and in thelaboratory (with marksmanship simulators).
