Practice Relating to Rule 8. Definition of Military Objectives
Section D. Weapons and weapon systems
Canada’s LOAC Manual (1999) considers that “military aircraft, weapons [and] ammunition” are “generally accepted as being military objectives”.
Canada’s LOAC Manual (2001) states in its chapter on targeting: “The following are generally accepted as being military objectives: … military aircraft, weapons, ammunition”.
In its chapter on naval warfare, the manual states:
Enemy warships, military aircraft, auxiliary vessels, and auxiliary aircraft … are legitimate targets and may be attacked. Such vessels and aircraft may not be attacked if they are protected under paragraph 41 [of the San Remo Manual on International Law Applicable to Armed Conflicts at Sea, which states that: ‘Attacks shall be limited strictly to military objectives’]”.
