Handbook of Terrorist and Insurgent Groups: A Global Survey of Threats, Tactics, and Characteristics examines the most current and significant terrorist and insurgent groups around the world. The purpose is to create a descriptive mosaic of what is a pointedly global security challenge.The volume brings together conceptual approaches to terrorism, insurgency, and cyberterrorism with substantive and empirical analyses of individual groups, organisations, and networks. By doing so, not only does the coverage highlight the past, present, and future orientations of the most prominent groups, but it also examines and illustrates their key characteristics and how they operate, including key leaders and ideologues. Highlighting specific, individual groups, the chapters collectively present a robust and comprehensive outlook on the current geography of terrorism and insurgency groups operating in the world today.This comprehensive volume brings the collective expertise and knowledge of more than 50 academics, intelligence and security officials, and professionals together, all of whom are considered subject experts in their respective areas of research and practice. The volume is based on both desk-based and fieldwork conducted by experts in these areas, incorporating analyses of secondary literature but also the use of primary data including first-hand interviews on the various groups' regions of operation, their tactics, and how their ideologies motivate their actions.
