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.
House demolition
House demolition is primarily a military tactic which has been used in many conflicts for a variety of purposes. It has been employed as a scorched earth tactic to deprive the advancing enemy of food and shelter, or to wreck the enemy's economy and infrastructure. It has also been used for purposes of counter-insurgency and ethnic cleansing. Systematic house demolition has been a notable factor in a number of recent or ongoing conflicts including the Israeli–Palestinian conflict, the Darfur conflict in Sudan, the Iraq War, the Vietnam War, the Yugoslav wars and the Caucasian conflicts of the 1990s.
