In this publication, Matthew Cancian offers a much-needed framework for evaluating the effectiveness of Special Operations Forces (SOF) in the effort to professionalize partner forces. The author proposes that structured surveys related to tactically oriented training outcomes can yield significant information about partnered forces’ evolution over time. Since SOF often operate in politically sensitive or denied environments, it becomes all the more necessary to conduct the kind of research he describes in this monograph to assess the best strategies for improving partner capabilities while recognizing the limitations imposed by their sociopolitical realities. Effectiveness is ultimately a political as well as military condition, and in this monograph Matthew Cancian offers an excellent approach to evaluating both.
