This book offers a multidisciplinary treatment of targeting. It is intended for use by the military, government legal advisers and academics.  The book is suitable for use in both military training and educational programs and in Bachelor and Master degree level courses on such topics as War Studies and Strategic Studies. The book first explores the context of targeting, its evolution and the current targeting process and characteristics. An overview of the legal and ethical constraints on targeting as an operational process follows. It concludes by surveying contemporary issues in targeting such as the potential advent of autonomous weapon systems, ‘non-kinetic’ targeting, targeting in multinational military operations and leadership decapitation in counter-terrorism operations. The deep practical experience and academic background of the contributors ensures comprehensive treatment of current targeting and use of force issues.
