Hors de combat (French:[ɔʁdəkɔ̃ba]; lit.'out of combat') is a French term used in the laws of war to refer to persons who are incapable of performing their combat duties during war. Examples include persons parachuting from their disabled aircraft, shipwreck survivors, as well as the sick, wounded, detained, or otherwise disabled. Intentional hostility from assumed persons removes any legal protection on their part.
