Practice Relating to Rule 10. Civilian Objects’ Loss of Protection from Attack
Section A. Civilian objects used for military purposes
South Africa’s LOAC Teaching Manual (2008) states:
Objects, which are normally civilian objects, can, according to the military situation, become military objectives (E.g. a house or a bridge being used for tactical defence purposes).
Civilians can lose their protection under the LOAC [law of armed conflict] for such times as they take a direct part in hostilities. Civilian objects used for hostilities similarly lose their protection.
