A five-day field trial was undertaken at CFB Valcartier, PQ, over the period of 24 to 28 October 1999. Fifty-eight regular force personnel were required to complete a standardized rifle night marksmanship test while using monocular (AN/PVS-14), biocular (AN/PVS-7, AN/PVS-504) and binocular (AN/AVS-502) Night Vision Goggles (NVGs) and a laser aiming aid (Carbine visible laser) during live bush lane target engagements with the C7A1 rifle. Secondary aims included: investigation to determine if night target engagement performance and user acceptance differed according to night vision goggle device; investigation to determine if night target engagement performance could be improved with the use of a visible laser aiming device; and investigation to determine if the latest biocular NVG (AN/PVS-7) provided a quantitative and qualitative improvement in target engagement performance over the older biocular (AN/PVS-504) NVG. Human factors tests included target detection and target engagement accuracy, user acceptance and NVG design criteria of importance. Data collection included questionnaires, performance measures and HF observer assessments. The trial results confirm that target detection performance varied according to NVG type. The Generation III NVGs (AN/PVS-7, AN/PVS-14, and AN/AVS-502) performed significantly better than the older Generation II AN/PVS-504 NVG for target detection. The results of this bush-lane study did not indicate a significant difference in target detection
