Practice Relating to Rule 106. Conditions for Prisoner-of-War Status
Section A. Distinction from the civilian population
Ukraine’s IHL Manual (2004) states:
Combatants are obliged to distinguish themselves from the civilian population while they are engaged in an attack (or in a military operation preparatory to an attack), at least by carrying their arms openly.
If a combatant falls into the power of an adverse party, he shall be entitled to the status of a prisoner of war.
