Cameroon’s Instructor’s Manual (1992) states that the restrictions contained in the 1980 Protocol II to the Convention on Certain Conventional Weapons must be scrupulously applied in order to avoid civilian casualties. The manual provides, therefore, that the use of mines, booby-traps and other devices must follow the rules on the prohibition of indiscriminate use and on the taking of all feasible precautions to protect civilians as provided for in Article 3 of the 1980 Protocol II to the Convention on Certain Conventional Weapons.
