During the Battle of Iwo Jima in February and March 1945, Japanese deception included dummy tanks sculpted out of the island's soft volcanic rock. At the Japanese-held airfield in Tianhe District, China, the Japanese painted on the ground the image of a B-29 Bomber that appeared to be on fire. Their intent was for the painted image to appear real to high-flying aircraft, which would lower their altitude in order to investigate, thus making them targets for Japanese anti-aircraft fire. In addition, the Japanese made extensive use of bamboo-framed dummy aircraft to project airpower and protect their remaining aircraft, straw dummy soldiers and wood weapons that made defensive works appear to be manned, and wood dummy tanks to make infantry soldiers appear to have more combat power than they actually possessed.
