In this monograph, Robert Haddick examines a variety of emerging technologies and techniques that could improve the sustainment and effectiveness of distributed SOF operations, especially in access-denied environments. He begins by describing a challenging yet plausible notional unconventional warfare campaign scenario. He describes how current SOF planners would attempt to cope with this scenario under current doctrine and sustainment capabilities, explores current and emerging technologies that could provide new options and capabilities, and evaluates new technologies that promise to reduce logistic demand for distributed SOF operations. Haddick proposes research and development recommendations that provide SOF with capabilities that improve their capacity to execute clandestine UW campaigns in denied areas. This monograph helps close the gap between current conditions and what will be necessary in an access-denied future.
