Forty-eight M1 crewmen were tested in a temperate climate under conditions simulating 72-hour operations in an area contaminated with chemical agents. Over 50 per cent of the crewman voluntarily withdrew from the test, and maximum unit endurance did not exceed 32 hours. Two problems were found to be related to endurance failure. Soldiers who withdrew reported more intense symptoms associated with respiratory distress than did those who remained in the test. In addition, soldiers who withdrew experienced greater cognitive difficulties. Near-term countermeasures, assessed in some test iterations, showed no significant endurance-extending effects. Alternative solutions based on the identified problems were proposed.
