SALVO II. RIFLE FIELD EXPERIMENT
RESEARCH ANALYSIS CORP MCLEAN VA
Pagination or Media Count:
Tests were conducted to measure the relative hit probabilities of several multiple- and single-bullet rifle ammunitions in combatsimulated aimed rifle fire, to use them to compare ammunition effectiveness, and to examine the effects of various parameters, such as range, target-exposure time, TRAINFIRE qualification scores, etc., on the accuracy of aimed rifle fire. Average aiming error for the SALVO II system is 3.1 mils. If ricochet hits are included it is equivalent to 2.8 mils. Ricochet characteristics of the various ammunitions were different and account for deviations from expected ammunition performance. Better ricochet characteristics account for the 10 percent higher number of recorded hits achieved with .22-cal duplex ammunition compared with those with . 30-cal duplex ammunition. Multiple correlation results indicate that target- exposure time and presented area angular target size are the major factors determining hit probability in the SALVO II experiment. Other factors influencing hit probability, but to a very much smaller degree, are target activities such as movement and simulated firing. No accuracy differences ascribable to caliber i.e., .22 cal vs .30 cal were observed.
