High Quality Content by WIKIPEDIA articles! A scorched earth policy is a military strategy or operational method which involves destroying anything that might be useful to the enemy while advancing through or withdrawing from an area. Although initially referring to the practice of burning crops to deny the enemy food sources, in its modern usage the term includes the destruction of infrastructure such as shelter, transportation, communications and industrial resources. The practice may be carried out by an army in enemy territory, or its own home territory. It may overlap with, but is not the same as, punitive destruction of an enemy`s resources, which is done for purely strategic/political reasons rather than strategic/operational reasons. It was most famously used against Napoleon`s and Hitler`s armies invading Russia.
