Practice Relating to Rule 47. Attacks against Persons Hors de Combat
Section A. General
New Zealand’s Military Manual (1992) states: “A person who is recognised as, or who in the circumstances should be recognised as, hors de combat shall not be made the object of attack.” 
New Zealand, Interim Law of Armed Conflict Manual, DM 112, New Zealand Defence Force, Headquarters, Directorate of Legal Services, Wellington, November 1992, § 503(2) (land warfare); see also § 612(2) (air warfare).
Furthermore, the manual states that “making a person the object of attack knowing he is hors de combat” is a grave breach of the 1977 Additional Protocol I and a war crime. The manual explains that “this has always been a war crime under customary law”.
