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.

During the 2011 Libyan civil war, forces loyal to Moammar Gadhafi planted a large number of landmines within the petroleum port of Brega to prevent advancing rebel forces from utilizing the port facilities. Additionally Libyan rebel forces practiced scorched-earth policies when they completely demolished and refused to rebuild critical infrastructure in towns and cities formerly loyal to Moammar Gadhafi such as Sirte and Tawargha.
