How Allies Used Math Against German Tanks

Pepebuho writes "This an article about how the allies were able to estimate the number of German tanks produced in World War 2 based on the serial numbers of the tanks. Neat! Godwin does not apply."

  2. Same method used for Soviet Bombers by Attila+Dimedici · · Score: 4, Interesting

    This is very similar to the method that the CIA used to get a seat at the Big Boys table in U.S. Intelligence operations in the 1950s. When OSS became the CIA after WWII, they became a junior member of the U.S. Intelligence operations. In the 1950s, the Defense Intelligence Agency (I may have the wrong department, but it was the organization that got the lion's share of the U.S. Intelligence budget) estimated how many intercontinental bombers the Soviets had by looking at the size of the factories where they produced them and estimating how many the U.S. could produce in a factory of that many square feet. The CIA wanted to get a bigger chunk of the Intelligence budget, so they started looking at satellite photos of the Russian bombers. They noticed that the numbers on the tails of Soviet bombers went 1, 2, 3, 4, 5....11,12, 13, 14, 15,...21, 22, 23, 24, 25, etc. Based on this they determined that the Soviets had many fewer bombers than earlier estimates. When other sources provided corroborating evidence, the CIA was able to get a bigger chunk of the Intelligence budget. Of course, they then made the same sort of mistake in estimating ICBMs that they had corrected with this methodology.

  3. Nothing very new in this - Verdun by Kupfernigk · · Score: 4, Interesting

    It can work backwards. At the Battle of Verdun in WW1, Petain (who only became an anti-hero in WW2) rotated French regiments through the Verdun front (a system called noria) so that whole regiments would not be destroyed. The Germans left their troops in battle till all were killed. From captured French uniforms and the number of regiments recorded, they greatly over-estimated the size of the French defense.

  4. Houses too by mccalli · · Score: 3, Interesting

    My dad drove a tank in WWII. I believe one of the Churchills but I'm no war historian and I'm happy to be shown otherwise. He was in the Normandy landings and eventually in the invasion of Berlin too.

    Thing is, the German tanks had bigger guns and longer ranges - significantly longer. There was apparently a speed advantage to the British tank (I'm going by what I was told, again I'm not a WWII-buff by any means) though, so what they used to do was lure the German tank into a village, then drive round back of them. The German guns were so big they couldn't turn them in in a normal street with buildings on either side whereas the smaller British tank certainly could. Not sure this was by design, but they took any advantage they could of course and I'm told that this trick was used by my dad a number of times.

    Cheers,

      I am a WWII buff.

      If your dad drove a tank that was faster than German tanks, it probably wasn't a Churchill. Could it have been a Cromwell? Those also showed up in Normandy, were still in service at the end of the war, and were pretty fast.

      The tactic you describe was used against the bigger German tanks, as the ones the size of most Allied tanks didn't have especially long guns. He probably used it the most in the Normandy fighting, as that's when the Germans concentrated heavily against the British and Canadian armies.

  5. Meth by Robotron23 · · Score: 4, Interesting

    I read the title as 'Meth':

    For once a misreading made perfect sense in the summary title's context: use of amphetamines throughout World War II on land and air personnel is well-documented. There's a phrase one hears infrequently that amphetamines 'won the Battle of Britain' - fending off constant attack from the Luftwaffe made necessary the use of stimulants as hiring and training a new pilot took too long. Whether it really did tip the scales in that battle we'll never know. As one would expect abuse orose within both Allied and Axis forces, and the spike in use persisted after the war. The Vietnam conflict saw American troops use methamphetamine very widely, and today the drug is popular amongst the poor as a relatively inexpensive stimulant.

    If there's anything that isn't widely known by the public and merits publicizing it's history of drugs such as this in the context of 20th century events like warfare. What laid ground for a forerunner to the modern drugs situation to me represents a phenomena of greater gravity than the serial numbers of tanks which one would expect would be used simply through using good old oxymoronic common sense.

    Presently there's a drug by the name of 'Modafinil' which mimics amphetamine but removes almost entirely the euphoric element and much of the crash that accompanies sudden cessation. It has been around for a number of years, and sees much use in modern conflicts. It also has much off-label use, and has even been used by astronauts to cope with heavy exercise regimens.

    That's exactly why the Soviet Navy gave their ships non-sequential pennant (hull) numbers, and frequently re-assigned them. They would also sometimes paint one number on one side of the bow, and different on the other.
     
    Security is a difficult business.
     
    Intelligence can also be a weird business... I once read an account of how the CIA broke into a warehouse rented by the Soviet Embassy in Mexico City in order to examine (very closeup and very clandestinely) a high fidelity mock-up/prototype of a satellite the Soviets had on tour. The idea was to gather information on any real cable, connectors, or other hardware on the bird - as well as to collect any serial numbers, drawing numbers, etc.. that they could find. (It's not uncommon for such to contain 'real' items that have been discarded from production or operational use.)
     
    You'd be surprised what a trained and knowledgeable analyst can derive from just a few seemingly unconnected bits of information.

    That's the thing though. We were fighting Germany and Japan. We're not fighting Afghanistan, we're fighting Al Qaeda. If you firebomb cities in Afghanistan, you're mostly destroying your allies. It's an entirely different sort of war. It's a war you don't want to fight because it's almost impossible not to make a huge mess and accomplish nothing.

    If North Korea decides to invade South Korea, that's the sort of war we can fight. One with a clear goal and somebody who has the kind of authority needed to stop hostilities once you negotiate a peace (even if it's unconditional surrender). You can't do that with insurgencies, because there is nobody in charge and they're run more like criminal gangs than actual armies.

    in all seriousness WHO THE BLEEP EVER HEARD OF THAT PRANK BEFORE

    It's a simply ploy on misdirection. It's been around in one form or another for years. Back in grade school, we had word problems that played on this where we had to select the proper information to solve a math problem.

    It can be done/demonstrated easier with coins and not harming any animals. Assemble 3 coins (US currency) a penny, a nickle, and a quarter.

    Now tell them that Johny's mom had three kids. Point to the penny and say the name Penny, point to the nickle and say the name Nicolas, then point to the Quarter and ask what the third one's name is. Most people will spend a considerable time attempting to work quarter or some variation of it into a name even after repeating that Johny's mom had three kids. Eventually they give up.

    (in case anyone is wondering, the third one's name if Johny- as in Johny's mom). It's a little easier then how far can a dog run into the woods.
