Practice Relating to Rule 1. The Principle of Distinction between Civilians and Combatants
Section A. The principle of distinction
Ukraine’s IHL Manual (2004) states:
Principle of distinction means that during preparation for and conduct of combat a clear distinction must be made between civilians and combatants [and] between civilian objects and military objectives, with a view to ensuring protection of the civilian population and civilian objects from the consequences of hostilities and to concentrating the actions of forces exclusively against the enemy’s military objects.
