The past two decades have witnessed the rapid proliferation of private military and security companies (PMSCs) in armed conflicts around the world, with PMSCs participating in, for example, offensive combat, prisoner interrogation and the provision of advice and training. The extensive outsourcing of military and security activities has challenged conventional conceptions of the state as the primary holder of coercive power and raised concerns about the reduction in state control over the use of violence. Hannah Tonkin critically analyses the international obligations on three key states - the hiring state, the home state and the host state of a PMSC - and identifies the circumstances in which PMSC misconduct may give rise to state responsibility. This analysis will facilitate the assessment of state responsibility in cases of PMSC misconduct and set standards to guide states in developing their domestic laws and policies on private security.

Critically analyses states' obligations to control PMSCs in armed conflict and assesses how PMSC misconduct may lead to state responsibility.

This book brings to fruition the research done during the CEA-ISCTE project ‘’Monitoring Conflicts in the Horn of Africa’’, reference PTDC/AFR/100460/2008. The Portuguese Foundation for Science and Technology (FCT) provided funding for this project. The chapters are based on first-hand data collected through fieldwork in the region’s countries between 4 January 2010 and 3 June 2013. The project’s team members and consultants debated their final research findings in a one-day Conference at ISCTE-IUL on 29 April 2013. The following authors contributed to the project’s final publication: Alexandra M. Dias, Alexandre de Sousa Carvalho, Aleksi Ylönen, Ana Elisa Cascão, Elsa González Aimé, Manuel João Ramos, Patrick Ferras, Pedro Barge Cunha and Ricardo Real P. Sousa.

Private Sicherheits- und Militärunternehmen erleben seit den 1990er Jahren einen außerordentlichen Boom und sind derzeit eines der spannendsten Phänomene in den internationalen Beziehungen. Die Palette der von ihnen angebotenen Dienstleistungen ist groß. Sie reichen von logistischer Unterstützung über Aufklärung bis hin zu Kampfeinsätzen. Zu ihren Kunden zählen Regierungen, Wirtschaftsunternehmen, internationale Organisationen, NGOs, humanitäre Organisationen sowie Privatpersonen. Gegenwärtig lässt sich an den Auseinandersetzungen im Irak sowohl die Aktualität wie auch die Brisanz ihres Einsatzes illustrieren, gibt es doch Anzeichen dafür, dass Beschäftigte solcher Unternehmen u.a. in die Folterung von Gefangenen verwickelt sind. Die Beiträge des Sammelbandes aus der Feder nationaler wie internationaler Expertinnen und Experten beschreiben und analysieren verschiedene Typen von privaten Sicherheits- und Militärunternehmens, ihre Dienstleistungen und die Umstände, die ihren Boom befördert haben. Sie diskutieren die Vor- wie auch die Nachteile ihres Einsatzes und beschreiben Instrumente, die die Tätigkeit dieser Unternehmen stärker reglementieren und kontrollieren könnten.

Mercenaries are more powerful than experts realize, a grave oversight. Those who assume they are cheap imitations of national armed forces invite disaster because for-profit warriors are a wholly different genus and species of fighter. Private military companies such as the Wagner Group are more like heavily armed multinational corporations than the Marine Corps. Their employees are recruited from different countries, and profitability is everything. Patriotism is unimportant, and sometimes a liability. Unsurprisingly, mercenaries do not fight conventionally, and traditional war strategies used against them may backfire.

The book concludes with an assessment of the complexities surrounding responses to security privatization - and an exploration of when, and whether, it should be promoted rather than prevented."--BOOK JACKET.

The legitimate use of force is generally presumed to be the realm of the state. However, the flourishing role of the private sector in security over the last twenty years has brought this into question. In this book Deborah Avant examines the privatization of security and its impact on the control of force. She describes the growth of private security companies, explains how the industry works, and describes its range of customers – including states, non-government organisations and commercial transnational corporations. She charts the inevitable trade-offs that the market for force imposes on the states, firms and people wishing to control it, suggests a new way to think about the control of force, and offers a model of institutional analysis that draws on both economic and sociological reasoning. The book contains case studies drawn from the US and Europe as well as Africa and the Middle East.
