Practice Relating to Rule 148. Reprisals in Non-International Armed Conflicts
Cameroon’s Instructor’s Manual (1992), in a part dealing with “victims of civil war”, states: “During all military operations, offensive or defensive, certain forms of conduct are prohibited and remain contrary to the law of war. Examples [are] … to carry out reprisals against populations.”

At the CDDH, in its explanation of vote on draft Article 10 bis of the Additional Protocol II, the delegation of Cameroon stated that it had
voted for this provision in the belief that a blanket prohibition of reprisals would not be feasible. No State could reasonably be asked to stand by and allow grave and repeated breaches of the Conventions or the Protocols by its adversary. The prohibition of reprisals should … be limited to certain well-defined cases, restrictively enumerated.
