Practice Relating to Rule 57. Ruses of War
Argentina’s Law of War Manual (1969) provides: “Stratagems or ruses of war and the employment of methods necessary for obtaining information about the enemy and the country are considered as lawful.”
The manual also states:
The observation of the principle of good faith must be constant and inalterable in dealings with the enemy. Consequently, the use of ruses and stratagems of war shall be legitimate as long as they do not imply the recourse to treachery or perfidy.
Argentina’s Law of War Manual (1989) states that stratagems are “acts which are intended to mislead an adversary or to induce him to act recklessly but which infringe no rule of international law and which are not perfidious”. It gives examples of stratagems, such as camouflage, mock operations and false information.
