This volume is based upon the discourse, dialogue, and outcomes of the 2nd Senior Unconventional Warfare (UW) and Resistance Seminar, hosted by the Joint Special Operations University (JSOU); Baltic Defence College (BALTDEFCOL); U.S. Special Operations Command Europe (USSOCEUR); Estonian Special Operations Forces; and the Centre for Applied Studies, Estonian National Defence College. From 4–6 November 2014, a multinational and interagency group of academics and practitioners gathered at the Baltic Defence College in Tartu, Estonia to discuss and debate the study and practice of UW and resistance. This book’s aim is to spark intensive discussion on both UW and counter-UW approaches, doctrine, and capabilities.
