Attacks on parachutists, as defined by the law of war, is when pilots, aircrew, and passengers are attacked while descending by parachute from disabled aircraft during wartime. The practice is widely considered to be inhumane and, consequently, such parachutists are considered hors de combat under the Protocol I addition to the 1949 Geneva Conventions, meaning that attacking them is a war crime. Firing on airborne forces who are descending by parachute (i.e. paratroopers) is not prohibited.[1]
