International terrorism remains a significant threat to the peace of the world. Weapons using various materials and delivery systems have been directed against cities and infrastructure, and other materials are postulated to be usable within the near future. Some of these materials are unusual or exotic, while some are modifications of materials used daily for other purposes: biological, chemical, radiological, nuclear and explosive. These materials pose a safety challenge for first responders, slowing the response and potentially killing scarce trained personnel. This book provides information about how leading agencies across the NATO membership are preparing to confront and respond to terrorists deploying Weapons of Mass Destruction (WMD), Weapons of Mass Killing (WMK) and Weapons of Mass Disruption (WMDi). Based on contributions by experts from NATO member states, Israel and the Russian Federation, this book offers information on fourth generation warfare as a new challenge to first responders. It also provides a variety of insights into methods for preparing for and responding to WMD-, WMK-, and WMDi-events, using new technologies and strategies. Furthermore, the book offers solution for restoring the community to functioning after such a major terror attack. Topics include preparing, planning, operations, equipment, training and unique applications of existing technologies for countering terrorist attacks against cities and their infrastructure.
