I came across an article on the news about dummy tanks used for the D-DAY invasion to miss lead the enemy forces as to where the allies were going to land. I did a little more research and found out dummy decoys were used as early as WWI. So I know there are a lot of modelers here that know a lot of military history, but I thought that this might interest them as well as those of us who are not as knowledgeable. Besides the picture I included blows your mind till you see that it is a balloon. I found a Chinese website that sells yard balloons including tanks for a price. Imagine these at Halloween, or Christmas. Here is an article about the decoys for the wars: http://en.wikipedia.org/wiki/Dummy_tanks
