INDEX OF PROXIMITy: A TECHNIQUE FOR SCORING SUPPRESSIVE FIRE

A statistical procedure has been developed which assesses and expresses in an index number the proxtmity to the target of tmpact points for serially fired small arms rounds. Factors which are thought to contribute to fire suppression of the individual have been included in the index so that it may be used as a scoring technique for suppressive fire. The incle.x can be used to compare individual f. !re missions as well as two or more groups of fire missions. The index has been designed pr~rily for use n R & D field tests of man-weapon-ammunition systems in which comparisons need to be made of the performance of different systems. It should be particularly useful in comparing missions in which there is a tendency toward good correction, but where the number of actual hits on the target is quite small. Use of the index requires a knowledge of the projectile impact points with respect to the target location.
