English: This night observation device was the largest and had the greatest range of any of the family of sights developed by the U.S. Army Electronics Command's Night Vision Laboratory. Mounted independent of a weapon on the ground or on a standing tripod, this device was used to detect the presence or activity of an enemy in faint sky glow, moonlight or starlight at distances up to 1,200 meters.
