This Law of War Deskbook is intended to replace, in a single bound volume, similar individual outlines that had been distributed as part of the Judge Advocate Officer Graduate and Basic Courses and the Operational Law of War Course. Together with the Operational Law Handbook and Law of War Documentary Supplement, these three volumes represent the range of international and operational law subjects taught to military judge advocates. These outlines, while extensive, make no pretence of comprehensively covering this complex area of law. Our audience is the beginning and intermediate level practitioner; our hope is that this material will provide a solid foundation upon which further study may be built.
