Practice Relating to Rule 141. Legal Advisers for Armed Forces
Côte d’Ivoire’s Teaching Manual (2007) provides in Book III, Volume 2 (Instruction of second-year trainee officers):
The military or civilian authorities have the duty to know international humanitarian law.
This is therefore an individual obligation of the military officers who, however, in view of the increasing complexity of that law, can make use of the help of legal advisers.
