Practice Relating to Rule 106. Conditions for Prisoner-of-War Status
Section C. Situations where combatants cannot distinguish themselves
At the CDDH, Egypt stated that “the right to disguise was confined to the combatants of liberation movements; regular combatants were not released … from the obligation to wear uniform during military operations – failure to do so would be to commit an act of perfidy”. It further explained that it interpreted the expression “military deployment” as meaning “the last step when the combatants were taking their firing positions just before the commencement of hostilities; a guerrilla should carry his arms openly only when within range of the natural vision of his adversary”.
