Abstract : Friendly forces passing through a minefield at night must be able to identify lights marking safe-passage corridors. Although the literature supplies some data that can be used as design criteria, they were not originally intended for a minefield situation. A study was conducted to verify the criteria and identify problems peculiar to minefield marking. Enlisted military subjects were tested with marker lights combining color-discrimination and acuity stimuli, in a darkened warehouse at night, to control atmospheric variables. The overall proportion of errors was .041 for the color trials, and .103 for the acuity trials. Although the acuity trials did not yield any firm conclusions, the study showed that errors in identifying colors were mainly confusions between amber and red. The report concludes with criteria for designing minefield marker lights, some of which are subject to further verification. (Author)
