Abstract
This chapter addresses the intersection of military and civilian forces in domestic security, taking its point of departure in the recent deployment of troops in anti-terror operations in France and a general shift toward stronger involvement of military forces in what have traditionally been police matters. We introduce the research field beginning with classic sociological texts from the 1950s with an emphasis on the scholarly debate from around 2000. Building on the literature we discuss different drivers behind the shift toward militarization of domestic security affairs. Finally, we present a variety of suggestions for approaches to further research in the field.
