How many principles are there under the Law of War?

The correct number of principles under the Law of War is indeed not nine. The Law of War traditionally outlines a framework for the conduct of armed conflict and the protection of persons not participating in hostilities. In many contexts, it is commonly recognized that there are a total of seven key principles that serve as a guideline for military operations. These principles include military necessity, distinction, proportionality, unnecessary suffering, humane treatment, honor of war, and discrimination.

These seven principles are critical as they guide military personnel in making ethical and legal decisions during armed conflicts, ensuring that operations are conducted in a manner that minimizes harm to civilians and respects international legal standards. Familiarity with these principles is essential for service members to maintain compliance with the Law of War and to uphold professional military conduct.
