The purposes of the Law of War are the conduct of armed hostilities on land is regulated by the law of land warfare which is both written and unwritten. It is inspired by the desire to diminish the evils of war by: a. Protecting both combatants and noncombatants from unnecessary suffering; b. Safeguarding certain fundamental human rights of persons who fall into the hands of the enemy, particularly prisoners of war, the wounded and sick, and civilians; and c. Facilitating the restoration of peace. "The Law of Land Warfare" (FM 27-10) provides authoritative guidance to military personnel on the customary and treaty law applicable to the conduct of warfare on land and to relationships between belligerents and neutral States. Although certain of the legal principles set forth herein have application to warfare at sea and in the air as well as to hostilities on land, this Manual otherwise concerns itself with the rules peculiar to naval and aerial warfare only to the extent that such rules have some direct bearing on the activities of land forces.
