Practice Relating to Rule 23. Location of Military Objectives outside Densely Populated Areas
Nigeria’s Military Manual (1994) states:
As regards the conduct of defence, it shall be organised primarily outside populated areas … Similar to when conducting an attack, where a choice is possible between general defence positions, the position to be selected shall be that which would cause the least danger to civilian persons and objects … Movements and locations presupposes that military units, except medical units, shall move or stay preferably outside populated areas if their presence would endanger civilian persons and objects. Movements which have to pass through populated area[s] shall be executed rapidly. Where it becomes expedient to locate military units temporarily near populated areas, such units shall be deployed so as to create the least possible danger to civilian areas. For longer lasting military locations, additional danger reducing measures shall be taken by the competent commander.
