Practice Relating to Rule 3. Definition of Combatants
On the basis of a reply by Iraq’s Ministry of Defence to a questionnaire, the Report on the Practice of Iraq considers that whoever joins the armed forces of a belligerent State is a combatant. It adds that this covers individuals of voluntary units, including members of organized resistance movements, who follow a belligerent party, whether their activities take place inside or outside their territory. The report recalls the four conditions laid down in Article 4(A)(2) of the 1949 Geneva Convention III and holds them to be explicit and specific criteria defining a combatant.
