Practice Relating to Rule 65. Perfidy
Section C. Simulation of being disabled by injuries or sickness
Ecuador’s Naval Manual (1989) states:
It is a violation of the law of armed conflict to kill, injure or capture the enemy … by feigning shipwreck, sickness, [or] wounds … A surprise attack by a person feigning shipwreck, sickness, or wounds undermines the protected status of those rendered incapable of combat … Such acts of perfidy are punishable war crimes.
