HUMAN FACTORS, 1983,25(6),693-700 A Study of Methods for Engaging Moving Targets

This research focused on two methods for engaging moving targets: tracking and trapping. Interest was in detennining the conditions under which either method would prove superior. It was hypothesized that a shooter's ability as well as the speed and range of the target might affect the outcome. All testing was accomplished on an M16Al rifle marksmanship simulator that pennitted the manipulation of the target's speed (velocity or duration) and range (apparent size). Based on a pretest, subjects were evenly divided into high- and low-ability groups. All subjects then fired two 24-target sequences, being instructed to track and then trap targets or vice versa. Following testing, subjects were required to indicate their preference for either tracking or trapping. Trapping proved superior for low-ability subjects and for the farthest (smallest) target moving at the slowest observed speed. Tracking proved superior for high-ability subjects and for the closest (largest) target moving at the fastest observed speed. Subjects generally preferred to use the method that produced better results
