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.
IT IS PROHIBITED to carry out any act of violence against Parlementaires and their escort, unless they carry out a hostile act first.
