Section B. Orders and instructions to ensure respect for international humanitarian law
Nigeria’s Operational Code of Conduct (1967) directs “all officers and men to observe strictly the following rules during operations. (These instructions must be read in conjunction with the Geneva Convention.)” It also states: “To be successful in our tasks as soldiers these rules must be carefully observed. I will not be proud of any member of the Armed Forces under my command who fails to observe them.”
