A 48-hour field experiment was conducted to determine the effects of sustained activity on the performance of tank crews in communication, driving, surveillance, gunnery, and maintenance activities. Moving surveillance and some driving activities showed statistically significant performance deterioration over a 48-hour period of work without sleep. The experiment showed that the diurnal rhythm of the subjects did not affect performance significantly. The results of the experiment support a broad conclusion that tank crews using present equipment can maintain operational proficiency during 48 hours of sustained activity.
