Sustained operations missions are performed in diverse environments. These environments include military command and control, process control, medical practice, and security surveillance. Research on the related fatigue effects of sustained operations is reviewed for each of these diverse environments. For military surge operations, both ground and airborne command and control operators show similar decrements in visual performance as a function of sleep loss. Other decrements include increased number of errors in vigilance tasks and reaction time tasks. In process control experiments, longer shifts resulted in more variance in reaction time to grammatical reasoning tasks. Night shift was associated with slower reaction times. For medicine, many studies compare performance on laboratory tasks across duty days as well as between participants who are rested and those who are not. Decrements occurred in reaction times. In security, both loss of sleep and work at night degrades operator performance.
