Practice Relating to Rule 65. Perfidy
Section D. Simulation of surrender
Under Italy’s IHL Manual (1991), grave breaches of international conventions and protocols, including “the perfidious use … of international protective signs”, constitute war crimes.
Italy’s LOAC Elementary Rules Manual (1991) states: “It is prohibited to feign a protected status by inviting the confidence of the enemy: … feigning of surrender.”
Italy’s Combatant’s Manual (1998) states:
Parlementaires, i.e. those who request to meet with the Commanding Officer of the enemy unit to discuss a ceasefire or to surrender, are protected by the “White flag”.
IT IS PROHIBITED to deceive the enemy by raising a white flag and then opening fire.
