The U.S. Department of Defense’s (DoD) Law of War Manual, first published in 2015, sets out the DoD’s authoritative interpretation of international law on matters relating to armed conflict. In recognition of its size, breadth, and the evolving nature of law and conflict, the Manual is also a living document that anticipates needing revisions and updates. In A Living Document, published by Just Security and the Reiss Center on Law and Security, leading scholars and practitioners reflect on how the Manual is keeping pace with its stated purpose and examine specific topics and rules where the Manual may be ripe for clarification or strengthening.
