Chapter 18 discusses the Manual’s coverage in Chapter XVIII of implementation and enforcement of the law of war. After discussing the extent of the obligations set forth in common article 1 of the Geneva Conventions, the Chapter assesses the Manual’s consideration of reasons that support the implementation and enforcement of the law of war. The Manual’s discussion of the duties of individual members of the armed forces, of the obligations of commanders, of the role of judge advocates and legal advisers, and of dissemination, instructions, and inclusion of the law of war in the planning of military operations is then considered in the next couple of sections. Thereafter, the Chapter looks at the Manual’s approach to State obligations with respect to violations of the law of war, including those perpetrated by the enemy. Compensation for violations, reprisals and war crimes are the subject of the concluding sections of the Chapter.
