Book Description
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.

Book Description
An evaluation was made of nighttime performances of tank gunners in localizing gun flashes with the fire control system of the M48 tank. Two night-simulated tests were conducted with 11 experienced and 20 inexperienced gunners, with these results: (1) In localizing 40 flash positions in a simulated periscope field-of-view, accuracy was fair within the reticle area but dropped off sharply outside this area; (2) in laying the main tank gun against those flashes, accuracy was poor. Error both in flash localization and in moving the gun controls contributed substantially to gun-laying error. It is concluded that the reticle of the M20 series periscopes (and presumably other periscopes and telescopes in which the reticle design covers only a small part of the field of view) is inadequate for localizing enemy gun flashes at night, and that the fire control system of the M48 series tank is inadequate for rapid laying of the main gun against nighttime targets that can be localized only by gun flashes.
