Introduced by the Vice Commander of USSOCOM, this Third Edition builds upon the success of the earlier versions and continues to incorporate the evolving policy guidance and strategic vision that guide ongoing interagency counterterrorism efforts. It provides an outline of organizations, missions, programs and relationships that comprise the interagency process. This manual provides insight and information regarding various counterterrorism organizations in the U.S. Government national security apparatus. Also included is an explanation of the expanded concepts of civilian power and their implications for Diplomacy and Development that emerged from the publication of the First Quadrennial Diplomacy and Development Review in 2010. Expanded sections on countering terrorist finance operations, interagency responses to cyber threats, and strategic communication reflect general acknowledgement of the importance of these capabilities. As before, updated collections of definitions, organizations, programs, and acronyms are included to provide the special operations warrior with an improved, practical, quick-reference guide to the interagency community.
