Effects of Continuous Military Operations on Selected Military Tasks

: New devices and sensors for night seeing and target acquisition have increased the capability of the U. S. Army for continuous operation extending through day and night. Although the soldier can continue to function under such conditions, his performance on critical tasks may be so degraded that his effectiveness is severely impaired. The present research was undertaken to determine the extent to which soldier performance is degraded on combat-related tasks, with the goal of developing techniques, work methods, and procedures for reducing such degradation if it occurs.
