Practice Relating to Rule 65. Perfidy
Section H. Simulation of protected status by using other internationally recognized emblems
France’s LOAC Summary Note (1992) prohibits perfidy and states: “It is forbidden to feign a protected status by inviting the confidence of the enemy (abuse of distinctive signs and signals …).”

It also states that the “perfidious use of protected signs and signals” is a grave breach of the law of war and a war crime.
France’s LOAC Manual (2001) states: “Using a protective sign to deceive the enemy and reach an operational goal constitutes an act of perfidy.”

It further provides: “The perfidious use of any protective sign recognized by international law constitutes a war crime.”
