Practice Relating to Rule 65. Perfidy
Section G. Simulation of protected status by using the United Nations emblem or uniform
Argentina’s Law of War Manual (1989) provides that it is an example of perfidy “to make use of the signs, emblems or uniforms of the United Nations … so as to simulate a protected status”.
The manual adds that “the perfidious use of … recognized protective signs” is a grave breach of the 1977 Additional Protocol I and a war crime.
