Practice Relating to Rule 8. Definition of Military Objectives
Section A. General
Ecuador’s Naval Manual (1989) states:
Military objectives are combatants and those objects which, by their nature, location, purpose or use, effectively contribute to the enemy’s war-fighting or war-sustaining capability and whose total or partial destruction, capture, or neutralization would constitute a definite military advantage to the attacker under the circumstances at the time of the attack. Military advantage may involve a variety of considerations, including the security of the attacking forces.
