Abstract : Each of 12 infantrymen engaged targets at a nominal 500-meter range firing up to 17 rounds per target engagement of ball or tracer ammunition in daylight semiautomatically from an M14 rifle whose sights were biased two standard deviations either high or low in a test of the hypothesis that tracer ammunition would provide a marksmanship aid. Analyses of hit and rate of fire data showed no statistically significant differences as a function of either ammunition type of sight bias. (Author)
