The conflict over the expression of aggressiveness in wartime America is described. Five ex-soldiers are presented as examples of men who adjusted poorly in training camps for that reason. Although their psychiatric histories and the results of psychological studies show great variability in apparent aggressiveness, nevertheless, all the examples had strong evidence of inhibitions, frustation, and conflict both in regard to aggressiveness itself and psychosexual adjustment. They demonstrate the need for conscious cultural direction with the co-operative advice of sociologists, anthropologists, and psychiatrists.
