Practice Relating to Rule 65. Perfidy
Section J. Simulation of protected status by using flags or military emblems, insignia or uniforms of neutral or other States not party to the conflict
Ukraine’s IHL Manual (2004) states that an example of perfidy is “the feigning of protected status by the use of signs, emblems or uniforms of … neutral or other States not Parties to the international armed conflict”.
The manual further states: “Perfidious use of distinctive emblems (insignia or signals) of persons and objects protected by the laws of war shall constitute serious [violations of international humanitarian law].”
