Target indication in darkness

Previous studies of target indication have been conducted in daylight. In this field experiment two kind of indication methods used in daylight were tested in darkness. The two methods were normal verbal communication over radio and a visual matching method giving the azimuth to the target with high accuracy. The second method was modified to avoid dazzle of the soldier´s NVG. The result showed that the free speech method is acceptable during good light conditions when the target is easy to detect. In low light condition, when the target is more difficult to detect, the visual matching method gives a better support. The soldiers spontaneously understood how to use this method and were able to use it without previous training. This method gave also them the feeling of always finding the target
