A five-day field trial was undertaken at Fort Benning, Georgia in December of 2001. Sixteen volunteer regular force infantry soldiers completed a standardized marksmanship test while using different on-bore and off-bore vision enhancement, aiming, and illumination devices, during the day and at night, in a repeated measures design. Accuracy was tested on the Fort Benning Malone 18 combat range. Engagement serials included 15 static and 10 moving targets. Target distance ranged from 35m to 300m, and exposure times ranged from three to eight seconds. Human factors (HF) tests included assessment of rifle firing performance, illumination, visual acuity and contrast sensitivity, compatibility, user acceptance, and criteria of importance. Data collection included questionnaires, focus groups, performance measures, and HF observer assessments. This field trial assessed the capabilities of conventional on-bore and off-bore systems for static and moving target engagements using live ammunition. The target engagement capabilities for four conventional on-bore sights (iron, C79, red-dot, and holographic), three off-bore sights of different magnification (Land Warrior 1x Digital Video Sight (DVS), Land Warrior 3x DVS, the Defence and Civil Institute of Environmental Medicine (DCIEM) 3.4x sight, a thermal on-bore sight, and a thermal off-bore sight during daylight were recorded. The capabilities four image intensification (II) night vision goggles (NVG’s): monocular AN/PVS-14, biocular
