Abstract: There is a concern that some armored vehicles currently in use by the U.S. Army do not meet the requirements for ground vehicles found in MIL-STD-1472F. This report attempts to highlight the requirements for ventilation in closed vehicle systems, such as military tactical vehicles. In this process, numerous quantitative metrics are provided to indicate how those requirements should be addressed by evaluating the current military and commercial standards, as applicable. We present a review of selected system evaluations performed in the past and evaluate appropriate test procedures and modeling methodologies to determine future requirements for ventilation in tactical military vehicles. In order to understand the ventilation requirement in MIL-STD-1472F and to determine if additional or substitute requirements would better identify ventilation safety in armored vehicles, the following questions will be addressed: (1) How was this requirement developed? (2) What is the impact of not meeting this requirement in terms of human performance and impact on mission performance? (3) Are there better measures for acceptable vehicle ventilation?
