Indonesia
Practice Relating to Rule 5. Definition of Civilians
Indonesia’s Air Force Manual (1990) states: “Unlawful combatants are persons who participate in hostilities without authorization of the belligerent authority, including persons who are neither members of the armed forces nor of a militia.”
The Report on the Practice of Indonesia considers that this definition is compatible with the definition provided in Article 50(1) of the 1977 Additional Protocol I.
