The Effects of a 48-Hour Period of Sustained Field Activity on Tank Crew Performance.
Ainsworth, L. L.; Bishop, H. P.
This report describes the effects of 48 hours of sustained operations on the performance of tank crews in communication, driving, surveillance, gunnery, and maintenance tasks. It is a continuation of research to determine the endurance of troops using combat equipment with 48-hour capability. Proficienty tests were constructed for each type of tank-crew activity and made part of a 12-hour field exercise. Two groups of crews were used; one group negotiated a problem course four consecutive times for a total of 48 hours of continuous operation, and a control group followed the same procedure but had 24-hour rest periods between each 12 hours of operation. Only moving surveillance and some driving activities showed significant performance deterioration over a 48-hour period of work without sleep. Major conclusions were: (1) No serious performance decrements result from operating present tank equipment continuously for 48 hours without sleep; (2) Performance at night is not significantly affected by the subject's diurnal rhythm; (3) No major changes in present unit organization and tactical doctrine are necessary to accomplish continuous tank operations for periods up to 48 hours.
