Section A. General
Sierra Leone’s Instructor Manual (2007) states:
IHL principles are the best mankind can get in armed conflict situations …
Irrespective of rank, all members of the [Republic of Sierra Leone armed forces] must adhere to these rules religiously to avert prosecution for war crimes at the newly instituted Court Martial. The production of this manual is in part fulfilment of Government’s obligation to instruct its armed forces and civilian population alike in the provisions of international humanitarian law.
