One of the most important features of the Second Protocol is the 'enhanced protection' regime it establishes. This new category of cultural property is outlined in Chapter Three of the Second Protocol. Enhanced protection status means that the relevant cultural property must remain immune from military attack, once it is inscribed on the List of Cultural Property Under Enhanced Protection. While the 1954 Hague Convention requires States not to make any cultural property the object of attack except for cases of 'military necessity', the Second Protocol stipulates that cultural property under enhanced protection must not be made a military target, even if it has (by its use) become a 'military objective'. An attack against cultural property which enjoys enhanced protection status is only excusable if such an attack is the 'only feasible means of terminating the use of property that way' (Article 13).
