When do Marines adhere to the principles of the Law of War?

Marines adhere to the principles of the Law of War while accomplishing any mission, as the Law of War is a fundamental framework that governs the conduct of military operations. This encompasses all actions taken during military service, not just those that occur in combat. The principles are in place to ensure ethical conduct and compliance with international law, which includes the treatment of captured personnel, the protection of civilians, and the proportionality of military action.

Understanding that the Law of War must be followed in all situations reinforces the responsibility of Marines to act honorably and in accordance with legal obligations at all times. This training helps to instill a sense of accountability and encourages Marines to consider the implications of their actions in every operational context, whether in active combat, during training, or while engaging in support missions.

Following the Law of War outside of direct combat situations emphasizes that the principles are not merely procedural or conditional but are integral to military identity and behavior at all levels of engagement. This commitment to lawful conduct enhances mission credibility and preserves moral authority, ultimately contributing to operational effectiveness and the preservation of peace.
