Civil–military relations is an interdisciplinary area of research, reflecting the work of political scientists, military, sociologists, and historians. History and culture, the constitution of the state and the statutes and practices arising therefrom, changes in the international security environment, technology, the character of conflict, and the changing concept of “soldier-hood” all influence the civil–military relations of a state. There are many possible patterns of civil–military relations that provide different answers to the questions of who controls the military and how, the degree of military influence appropriate for a given society, the appropriate role of the military in a given polity, who serves, and the effectiveness of the military instrument that a given civil–military relations produces. Moreover, there is no “general” or “unified field” theory that successfully explains all of these patterns. For a variety of reasons, Samuel Huntington's institutional theory remains the dominant paradigm for examining civil–military relations. When it comes to the question of civilian control of the military, Peter Feaver’s agency theory corrects some of the flaws in Huntington’s theory. Morris Janowitz and the military sociologists also provide useful insights, especially regarding the question of who serves and related issues. In the case of concordance theory, critics argue that the definition of military intervention sets the bar too low to be meaningful. Ultimately, the patterns of civil–military relations affect national security because of their impact on strategic assessment.
