Effective representation of armored vehicles in simulation displays demands a careful evaluation of human perceptual capabilities. This holds especially true for computer generated target displays, which must provide sufficient detail to allow vehicle identification within limitations of computer processing time and display resolution. Even in image generation and display systems not incurring such limitations, the image detail need not exceed human perceptual and cognitive information processing capabilities. Providing excessive detailing of targets may, in fact, produce negative training by allowing those being trained to depend on information unavilable in combat for target identification. Results of research manipulating visible target detail in target identification training and its implications for target displays are discussed. Estimates are presented for the visibility of features of threat and friendly main battle tanks, based on analysis of past empirical research done under ideal visibility conditions and visibility data from past research.
