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 Three Alls Policy ("Sankō Sakusen") was a Japanese scorched earth policy adopted in China, the three alls being: ""Kill All, Burn All and Loot All"". Initiated in 1940 by Ryūkichi Tanaka, the "Sankō Sakusen" was implemented in full scale in 1942 in north China by Yasuji Okamura. According to historian Mitsuyoshi Himeta, the scorched earth campaign was responsible for the deaths of "more than 2.7 million" Chinese civilians.
