Necessity requires that the use of force must be essential to achieve a legitimate military objective, ensuring that actions taken are necessary and not excessive. This principle helps prevent unnecessary suffering and destruction.

Proportionality ensures that the violence used in warfare is proportional to the military advantage gained. This principle seeks to minimize collateral damage and limit harm to civilians and civilian infrastructure, thereby upholding ethical standards.
