Practice Relating to Rule 5. Definition of Civilians
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.
Civilian population – comprises of all persons who are civilian. The presence of individuals other than civilian persons does not deprive the population of its civilian character.
