Practice Relating to Rule 6. Civilians’ Loss of Protection from Attack
The Report on the Practice of the Philippines says that civilians lose their protection when they become hostile elements and contribute militarily to the insurgents’ cause. These civilians, who can serve for example as spies, couriers or lookouts, are qualified by the military as “sympathizers” or “communist terrorists” and can be the object of a direct military attack in villages influenced or infiltrated by the Communist Party of the Philippines. 
Report on the Practice of the Philippines, 1997, Chapter 1.2.
The Philippine Army Soldier’s Handbook on Human Rights and International Humanitarian Law (2006) notes in its glossary: “Civilian person – means any person who does not belong to the armed forces and does not take part in a ‘levee en masse.’ In case of doubt whether a person is a civilian or not, that person shall be considered as a civilian.”
