Practice Relating to Rule 106. Conditions for Prisoner-of-War Status
Section A. Distinction from the civilian population
New Zealand’s Military Manual (1992) provides:
With a view to ensuring protection of the civilian population, combatants are required to distinguish themselves from that population when engaged in an attack or preparing to mount an attack. Under the [Hague Regulations] this distinction depended upon a recognisable emblem and the carrying of arms openly. In the case of a State’s regular forces, the uniform worn by the forces strengthens the distinction.
