What basic Law of Armed Conflict principle is exemplified by needing approval to use certain munitions?

The principle of humanity in the Law of Armed Conflict emphasizes the need to minimize suffering and protect those who are not participating in hostilities. This principle is reflected in the requirement for approval to use certain munitions, as some weapons may cause unnecessary suffering or have indiscriminate effects that can harm civilians and combatants alike. By requiring approval for the use of specific munitions, military operations ensure that actions taken in conflict are in line with humanitarian standards and the ethical considerations of warfare, ultimately striving to preserve human dignity amid conflict.

In contrast, necessity relates to the military advantage sought by a particular action, proportionality addresses the balance between military gain and potential harm to civilians, and distinction focuses on the ability to differentiate between combatants and non-combatants during military operations. While these principles all play a role in the conduct of warfare, it is the principle of humanity that directly relates to the restrictions placed on the use of certain types of munitions to prevent undue suffering.
