Practice Relating to Rule 8. Definition of Military Objectives
Section H. Areas of land
Sweden’s IHL Manual (1991) states:
The definition [of military objectives contained in Article 52(2) of the 1977 Additional Protocol I] is intended to apply only to property or objects. Thus, for example, areas of land cannot be included; but this does not prevent an area objective if it is a matter of hindering an enemy advance by means of artillery fire or mining. Attacks on an area are permitted as long as the attack cannot be classified as indiscriminate.
