counter-terrorism operations are also studied in the Guide. Yet, as the book is also intended to be used by policymakers, legislators, government officials, and nongovernmental organisations, the editors included a chapter to discuss implementation of IHL, which sheds light on the different roles that States and international organizations have to play to increase the level of compliance with the rules. The Guide also contains a chapter written by the late Professor Robert Cryer on war crimes. With an in-depth introduction to various issues, reference to the case studies, and the State practice and case-law of national and international tribunals, the book has provided the readers with a valuable Guide illustrating how the IHL applies in practice.
