Bridging the gap in open-source studies between academic research and practitioner assessments, the authors discuss how these specific measures correspond with theoretical assessments of the effects they are due to produce, as well as with the expectations about their performance held by the deploying policy makers and their audience. As the war continues to unfold, and the reality on the ground, as well as emerging new data, mean a constantly shifting landscape, this volume will be a valuable resource for anyone interested in the conflict in Ukraine.
