Rubber Tanks and Sonic Trucks: the Ghost Army of World War II (hackaday.com)

szczys writes: While you may have heard of the Ghost Army that was used to fake troop movements during WWII, it's unlikely that you truly grasp the level of skill and success these elite groups achieved. At its surface, the story is about inflatable armies that could fool German intelligence from afar. That is one visual component, but there were many more involving sound and radio communications. Before the digital age, it was quite a trick making authentic audio recordings of military vehicle sounds on 2-mile long spools of very thin wire played back from vehicles outfitted with 500 Watt speakers. The A/V wasn't complete without radio communications spoofed to look like the Ghost Army was the real deal: this used the best of personal-morse-code-style impersonators. Elite groups trained in these phony arts operated throughout the European theater. Their story was top secret long after the war because the craft was considered a strategic asset well into the cold war era.

    There's a PBS documentary called The Ghost Army on Netflix about this that was made in 2013. This group was mostly Hollywood effects men and not soldiers, which made it especially dicey when the Germans actually advanced on their position quite rapidly at one point and they had to run like hell to get away as they had no real weapons or training to fight! The documentary is quite good if you're interested. It's an hour and seven minutes long.

    My thought exactly. And for all the releases and all the programs made about ww2,our governments are still inventing new lies about it and leaning on old lies to try and stop folk learning too much of the truth. If you have good walking legs and boots,can read maps and have some knowledge of major points in ww2 history,it's amazing what you can find in the southern half of the UK,but you have to be very careful cos being a tiny,cramped little island there are only so many places that current establishments and kit can be hidden .if you think you have some strange mapping anomolies in America,you want to try the UK.it's fun if you have a large collection of old maps and don't mind loads of trouble with supposed land owners,troops etc etc. You soon realise how much of our "history" is pure bs...

  3. Patton vs. Bradley by PolygamousRanchKid+ · · Score: 4, Interesting

    The big victory here, was that the Germans swallowed it hook, line and sinker. The Germans considered Patton to be the most formidable General that the Allies had. Unfortunately for Patton, he was on the shit-list, because he slapped a patient in a field hospital in Italy, who Patton mistakenly claimed was just suffering from cowardice.

    The German spooks heard of this, but discarded it quickly. Why would an Army sideline a brilliant General, just because he slapped a simple enlisted man? At any rate the "Patton Threat" really played a crucial role in all this, and helped the Normandy landings to be a success.

    Personal Note: I met an old German soldier a long time back, and we discussed the Normandy landings. He said, "We were waiting the whole time for Patton to land in Calais."

    Hey, fooled you, most awesomely!

      america sucks at how we treat our most talented generals. patton, macarthur, mcchrystal, petreus. all shut down by the paper pushers. its like the ultimate muscle-flexing by the civilian-controlled military. any time a military leader gets too powerful, knock him down a few rungs.

      I wondered the same myself. I think Patton slapping a GI is small stuff, probably did much more to piss off his superiors. Maybe they used that to create a red herring for German spies. Back when History Channel had history, one panelist commented if Patton was active on Normandy landings, they would have been more successful (not sure how to define success, airborne troops scattered about was a disaster but it really confused the Germans to exact beachheads). Speaking of ghost armies, I read that Saddam Hussein really believed he had formable WMDs and other weapon systems because his staff pumped up the numbers out of fear if they really told him he had no capable WMDs, they would be fired (literally). Apparently the American spooks fell for this as well.

      MacArthur however was treated with barely concealed contempt by the Australians (in particular)

      Very obvious lies inspired that. Taking credit for the actions of Australian forces long before he even turned up didn't go down well, but his entire career was like that - whatever real success he had did not seem to be enough for him to boast about.
      I don't know if it's true or not but the history taught to Chinese kids about the Korean war says that the Chinese decided to join in when MacArthur looked across the river into China with binoculars. Reality is likely to be different since the initial North Korean soldiers were the many Koreans that fought in the Chinese army in WWII anyway, and still in units, so effectively China was in the war on day one even if the force committed was a lot less than later.

      Petreus' end speaks for itself.

      Ironically due to wanting to "get his end in" with a journalist.

  4. We did the same thing in the Gulf War by OctobrX · · Score: 5, Interesting

    So I was a 93F with the 101st and one of the first things we did when we got in country was take a trip into Iraq. I was amazed at the HUGE giant amount of tanks I saw as we approached our area to run a met mission(fly a weather balloon lol). As we got closer and closer... I started to notice something. About 50 feet away, I noticed there were wires holding these inflatable vehicles down and let out the biggest cackle you'd ever heard. It was brilliant.

    We were there as a part of the GHOST ops to make it look like stuff was happening. Pretty smart if you think about it.
