 During the Battle of Okinawa, Japanese soldiers often used civilians as human shields against American troops.When the Japanese were concerned about the incoming Allied air raids on their home islands as they were losing their controlled Pacific islands one by one to the Allies in the Pacific War, they scattered major military installations and factories throughout urban areas, therefore, historians argued that Japan was using its civilians as human shields to protect their legitimate military targets against Allied bombardment.As a result, the U.S. Army Air Forces (USAAF) was unable to strike purely military targets due to the limitations of their bombsight, the mixing of military installations and factories with urban areas, and the widespread of cottage industry in Japan's cities.
