Practice Relating to Rule 117. Accounting for Missing Persons
Section A. Search for missing persons
Sierra Leone’s Instructor Manual (2007) states:
When tactically possible, searches must be carried out to look for “missing” (who may be wounded) to try to confirm their status and ultimately to keep their family informed. The same practice should be done to look for enemy listed as missing and also civilians reported as missing.
