Combatant is the legal status of an individual who has the right to engage in hostilities during an armed conflict. The legal definition of "combatant" is found at article 43(2) of Additional Protocol I (AP1) to the Geneva Conventions of 1949. It states that "Members of the armed forces of a Party to a conflict (other than medical personnel and chaplains covered by Article 33 of the Third Convention) are combatants, that is to say, they have the right to participate directly in hostilities." Consequently, on the other hand combatants, as a rule, are legal targets themselves for the opposite side regardless the specific circumstances at hand, in other words, they can be attacked regardless of the specific circumstances simply due to their status, so as to deprive their side of their support.
In addition to having the right to participate in hostilities, combatants have the right to the status of prisoners of war when captured during an international armed conflict. "While all combatants are obliged to comply with the rules of international law applicable in armed conflict, violations of these rules shall not deprive a combatant of his right to be a combatant or, if he falls into the power of an adverse Party, of his right to be a prisoner of war."
