Practice Relating to Rule 22. The Principle of Precautions against the Effects of Attacks
Madagascar’s Military Manual (1994) provides that in the conduct of all military operations, “constant care must be taken to spare the civilian population, as well as civilian objects”. 
Madagascar, Le Droit des Conflits Armés, Ministère des Forces Armées, August 1994, Fiche No. 6-O, § 11.
The manual further specifies that:
In order to limit civilian casualties and damage, the means of combat and weapons shall be adapted to the environment of the defence position … When the mission permits, information and effective warning must be given concerning defence measures which expose civilians to danger so that they can behave correctly during combat action.
