Practice Relating to Rule 6. Civilians’ Loss of Protection from Attack
All persons participating in military operations or activities are considered combatants [and proper targets for attack]. Those who do not participate in such actions are non-combatants. This distinction is not always easy to make. Uniformed, armed soldiers are easily recognizable. However, guerrillas often mix with the civilians, perform undercover operations, and dress in civilian clothes. Alertness and caution must guide you in deciding who is a combatant.
