"This edition enhances the earlier document by adding President Obama's National Security Strategy, expanding information in other areas such as in the Country Team and discussing the concept of the SOF professional operating as the 3-D warrior (defense, diplomacy, and development). This concept recognizes the importance of SOF as part of the sinew that binds together critical elements of national power and animates them under the most demanding conditions. As USSOCOM conducts a robust engagement campaign working with U.S. Government interagency components, the manual serves as an essential component of USSOCOM/JSOU's successful education curriculum that is focused on the interagency process. JSOU's Interagency Education Program and this manual make important contributions to the knowledge base and professional development of the SOF and interagency communities." -- Publisher's web site.
