Abstract : The accuracy with which mulated gun flashes cold be localized in the field of view of a tank periscope with the ad of 4 different gridtype reticles was determined. Each of 4 groups of enlisted men localized 48 single flashes using 1 of the 4 reticles. For 3 of the reticles data were also obtained from 3 groups of officers. Localizations were ade by reading the azimuth and elevation of the perceived flash positions. No differences of consequence in performance were obtained between groups using different reticles. Enlsted men performed best wth Retcle 4. Officers were found to loalze more accurately than enlisted men, and it was suggested that the difference might be attrbted to motivational fctors. The results were compared with those of an earlier study in which gun-laying accuracy against flashes was meaured. It was concluded that the use of a gd-type reticle would result in much greater gun-laying accuracy against fashes, if the tank fire control system were moified to enable the gunner to convert reticle readings accurately into lays of the gun.
