The need for research and recommendations about sleep logistics planning in sustained operations environments is discussed. The nap literature is reviewed and problems in experimental methodology, cross-study comparability, and generality are noted. To address these problems, a reserach programme has been initiated in which subjects assume the role of command-post operations officers in conditions anticipated for the sustained-intensive battlefield. The results of experiments from this programme indicate that continuous, intensive mental work combined with 2-3 days of sleep loss leads to greater performance decrements than those found in studies not emphasizing continuous cognitive demands. While the role of various countermeasures, including the effects of physical fitness, physical exercise and cognitive workload have been investigated, none of these interventions reduced the impairment in performance found in this scenario.
