Briefing on the Effects of the Protective Mask on Individual Combat Skills,

摘要

The immediate and prolonged effects of wearing a protective mask on an individual soldier's combat skills were studied in relation to seven different types of performance--rifle speed, obstacle running speed, clear running speed, rifle hits, binocular target detection, unaided target detection, radio, and driving vigilance. For each activity, one or more objective job-sample tests were constructed or existing tests modified and administered in three separate exploratory studies. Results of the study conducted at Fort Benning, Georgia with two groups of ten men each indicate (a) the immediate effect of the mask was interference with the combat activities, and (b) men did better, on the average, after they had worn the mask for five hours than they did after five hours unmasked.
