Armies have used decoys and lures for as long as people have been fighting wars. In World War II, all sides made use of deceptive techniques (for example, The Inflatable Tanks That Fooled Hitler.) While researching photographs from that era at the U.S. National Archives, I came across several images I had not seen before. They featured Japanese dummy aircrafts made of bamboo and wood planking. I later found several other photos of Japanese decoys from World War II—and images of a pair of mystery military vehicles (last two photos), that maybe you can help identify.
