The privatisation of defence assets and the outsourcing of military services from the armed forces to the private sector is an increasing trend. This book shows the extent to which many military functions and activities, ranging from military research to military consulting/training to operational support services, have been outsourced in the US and in Europe. While other books in this field largely cover the issues of Private Military Companies and of security contractors, this book focuses on technical and management services.This detailed study provides new and updated information on the ongoing privatisation of the defence sector and offers an original theoretical explanation of why the most modern armed forces throughout the world have come increasingly to rely on private companies for nearly everything they do. Contributing to a better understanding of military privatisation and its close connection to technological change, this book explains the complexity of the whole phenomenon and discusses its implications for national and international security.
