Scorched earth
A scorched-earth policy is a military strategy that aims to destroy anything that might be useful to the enemy while it is advancing through or withdrawing from a location. Any assets that could be used by the enemy may be targeted, for example food sources, water supplies, transportation, communications, industrial resources, and even the locale's people themselves.

The method was used during the Yugoslav Wars, such as against the Serbs in Krajina by the Croatian Army, and by Serbian paramilitary groups.
