Practice Relating to Rule 8. Definition of Military Objectives
Section A. General
Sweden’s IHL Manual (1991) states:
According to the definition [of military objectives contained in Article 52(2) of the 1977 Additional Protocol I], it is up to the attacker to decide whether the nature, location, purpose or use of the property can admit of its being classified as a military objective and thus as a permissible object of attack. This formulation undeniably gives the military commander great latitude in deciding, but he must also take account of the unintentional damage that may occur. The proportionality rule must always enter into the assessment even though this is not directly stated in the text of Article 52.
