Final answer:
The statement is true; the Law of War includes principles and regulations that apply during peacetime and occupation, seeking to maintain order and protect human rights.
Step-by-step explanation:
The statement that the Law of War also applies to duties during peacetime and occupation is true. The Law of War, or international humanitarian law, comprises rules that apply not only in times of armed conflict but also during peacetime, such as the prohibition of aggressive war and preparations for military engagements. During occupation, the Law of War imposes certain responsibilities on the occupying power to maintain order and civil life while respecting the rights of the occupied populace.
For instance, No State shall, without the Consent of Congress, keep Troops, or Ships of War in time of Peace, emphasizes the importance of maintaining peace and restricting military actions unless there are substantial threats that justify such actions.
