Which document or concept defines how force may be used in armed conflict according to international law?

• A. Geneva Conventions
• B. LAW OF WAR (DOD Manual)
• C. Rules of Engagement
• D. International humanitarian law

Answer: (B)

The Law of War (DOD Manual) provides the practical framework that translates international humanitarian law into how forces may be used in combat. It codifies core principles—distinction between military targets and civilians, necessity of force, proportionality to the military objective, and precautions in attack—and then shapes how units plan, engage, and conduct operations. This manual is what a military force uses to apply international law on the ground, turning broad rules into concrete procedures, targets, and limits. The Geneva Conventions are specific treaties within international humanitarian law that protect people who are not participating in fighting, such as civilians and prisoners of war; they do not, by themselves, lay out how force may be used in combat. International humanitarian law is the overall body of rules governing conduct in war, of which the Geneva Conventions are a part. Rules of Engagement are the operational directives that apply LOAC in a given mission but are not the law itself; they implement the law within a specific context.
