This innovative collection offers one of the first analyses of criminologies of the military from an interdisciplinary perspective. While some criminologists have examined the military in relation to the area of war crimes, this collection considers a range of other important but less explored aspects such as private military actors, insurgents, paramilitary groups and the role of military forces in tackling transnational crime. Drawing upon insights from criminology, this book's editors also consider the ways the military institution harbours criminal activity within its ranks and deals with prisoners of war. The contributions, by leading experts in the field, have a broad reach and take a truly global approach to the subject.
