Practice Relating to Rule 36. Demilitarized Zones
Section A. Establishment of demilitarized zones
Australia’s Defence Force Manual (1994) states:
Demilitarised zones are areas in which, by express agreement between the parties to the conflict, military operations are not conducted. The aim of these zones is common to that of non-defended localities. The differences between the two areas relate to how they are established and their situation. A non-defended locality may be created by unilateral declaration, whereas a demilitarised zone is created by express agreement between the parties. From the commander’s point of view, protection granted to each zone is identical. Therefore, as long as sufficient notice is given of the zones and they are adequately marked, they are protected from attack.
