Section A. The principle of distinction
Argentina’s Law of War Manual (1989) provides:
In any armed conflict, the right of the Parties to the conflict to choose methods or means of warfare is not unlimited. Therefore, it is prohibited to employ weapons, projectiles and material and methods of warfare of a nature to cause superfluous injury or unnecessary suffering and, besides, in order to guarantee the protection of the civilian population and civilian objects, the Parties to the conflict shall at all times distinguish between the civilian population and combatants and between civilian objects and military objectives.
