The Routledge Research Companion to Outsourcing Security offers an overview of the different ways in which states have come to rely on private contractors to support interventions.

Part One puts into context the evolution of outsourcing in Western states that are actively involved in expeditionary operations as well as the rise of the commercial security sector in Afghanistan. To explain the various theoretical frameworks that students can use to study security/military outsourcing, Part Two outlines the theories behind security outsourcing. Part Three examines the law and ethics surrounding the outsourcing of security by focusing on how states might monitor contractor behaviour, hold them to account and prosecute them where their behaviour warrants such action. The drivers, politics and consequences of outsourcing foreign policy are covered in Part Four, which is divided into two sections: section one is concerned with armed contractors (providing the provision of private security with the main driver being a capability gap on the part of the military/law enforcement agencies), and section two looks at military contractors (supporting military operations right back to antiquity, less controversial politically and often technologically driven). The final Part takes into consideration emerging perspectives, exploring areas such as gender, feminist methodology, maritime security and the impact of private security on the military profession.
