With regard to occupied territory, the manual provides:

Argentina’s Law of War Manual (1989) provides that “extensive destruction and appropriation of property not justified by military necessity and carried out unlawfully and wantonly” are grave breaches of the 1949 Geneva Conventions and war crimes.
