The anthropology of militaries in industrial countries is a relatively young discipline, which has seen significant growth since the end of the Cold War and the advent of the “new wars.” The chapter focuses on the anthropological analysis of social and cultural concerns related to (and derived from) the armed forces, war, and the provision for national security. It charts the main clusters of issues anthropologists are engaged with and explains the unique contribution of this discipline through the following themes: militarization, fieldwork, military organization and units, gender, military families, veterans, and medical anthropology. This chapter concludes with a discussion of anthropology’s contribution to military education.
