This paper analyzes military families as the intersection of two societal institutions, both of which make great demands on individuals in terms of commitment, loyalty, time, and energy. It shows the increasing conflict between these two "greedy institutions' due to various trends in American society and military family patterns. The demands that American armed forces make on members and their families are described, including the risk of injury or death, geographic mobility, family separations, residence in foreign countries, and normative constraints on the behavior of spouses and children. Also discussed are trends that are increasing the potential military/family conflict, including general changes in women's roles in society (especially labor force participation) and specific changes in military family patterns, such as increases in the number of married junior enlisted personnel, sole parents, active duty mothers, and dual-service couples. Actual and potential military adaptations to these changes are considered, with particular attention to their implications for institutional and occupational trends in the military.
