Practice Relating to Rule 85. The Use of Incendiary Weapons against Combatants
Section B. The use of incendiary weapons against combatants in particular
New Zealand’s Military Manual (1992) states:
There are no provisions on the use of incendiaries against combatants in [the 1980 Protocol III to the Convention on Certain Conventional Weapons]. The use of incendiary weapons to cause unnecessary suffering is prohibited. A value judgement must be made in particular circumstances to determine whether or not the suffering caused is unnecessary.
The manual also recalls that:
The UN Conference which negotiated the [1980 Protocol III to the Convention on Certain Conventional Weapons] was unable to agree on any requirement to protect combatants from the effects of incendiary weapons.
