I'm also not sure he understood the potential of the Otto-76 to shoot down smart munitions. Actually, John, you don't seem to have much of an understanding of how tanks work, or what the typical engangement ranges are. Five miles is right out. The longest range kill achieved by a tank to date is a 3,000m (roughlt 1.5 Statute Mile shot by a British Challenger II vs. an Iraqi T72 in the 1990-91 Gulf War. Even in open country like Iraq, the usual longest range for a Main Gun shot on an opposing tank was 2000m. In a European rural environment, the most likely engagement range would be 1000m. In more closed country, like, say, the Northeastern U.S., or Maritime Canada, engagement ranges as close as 50-100m are not unlikely. (Lots of irregular terrain, lots of trees & brush - European forests are like gardens in comparison.) Engagement ranges within urban areas are very short - usually on the order of 200m or so. Time of Flight for a main gun round to 2000m is about 1.2 seconds. Time of Flight to 200m, is (Wait for it - 0.12 seconds. Now, Sport, How much are you going to be dodging your SUV in 1.2 seconds. Be aware that you'll have to shave at least 0.5 seconds off of that for the driver's reaction time. Also consider that your millimeter-wave emitting SUV is ligking itself up like a neon sign in a part of the radio spectrum that nothing else is on. A couple of sinple horn antannae on the turret sides (Sort of like the old coincidence rangefinder ears) for DFing, and an omnidirectional antenna up with the Wind Sensor on the turret roof for general detection, and you won't, say, be able to hide your Tank-Killer SUV in Madman Morris's SUV Dealership's parking lot. And I especially agree with the last one - countries where all the citizens are heavily armed are not countries like Iraq, where people the ruler doesn't like get fed alive into shredding machines. So they aren't the kind of country we'd be needing to invade. However the question wasn't about poor countries, but middle-ranking ones, which I took to mean ones comparable to most european nations. Of such I'd say only Britian or France had the capacity to blunt a US attack, and only because they can both MIRV task-forces whilst they cross the atlantic. Nuclear buckshot will kill most things, and doesn't need to be too accurate either. Time of Flight of IRBM, 30 minutes. Speed of CVBG, 25 kts. Detection of launch, instantaneous. DSP Sats, y'know. Radius of circle that could contain the target - 12.5 Nautical Miles. U.S. Supply Convoys hump along at 20 kts, these days, so you're looking at a 10 NM circle there. Time of arrival of U.S. ICBM ('cause we're Nice Guys, and aren't going to unleacsh somethig on the order of 10 Trident MIRVs on your country, and only take out single targets, roughtly 1.0-1.5 hours after launch. Your Command Centers and missile bases, or Missile Sub ports don't move, and you made the mistake of going Nuclear first. -- Pete Stickney A strong conviction that something must be done is the parent of many bad measures. -- Daniel Webster |

To dodge a tank round all you need do is side-step half the width of your vehicle. At 1,000 yards the travel time of a 120mm APFSDS round is .52 seconds, Average human reaction time for someone doing nothing but sitting there and waiting for an event they have to respond to by flipping a switch is .3 to .8 seconds with a good 60% being above the ..5 second mark. Someone performing a complex task in reaction to a signal, like driving around and then having to dodge in a specific direction at a signal ranges from .35 to 1.5 seconds with 85% being over .5 seconds. - Henry and Rogers, 1960 Assuming that your system is so good that it can classify every round on the battlefield, tell what is coming and going, be scanning the air for cluster bombs and rockets and take 0 seconds to illuminate a light on the dash telling you which way to swerve, it won't help you at all. 85% of your vehicles will be killed by the first shot because they didn't respond in time and none of the rest will be able to get that half width in the .15 seconds they have to move the vehicle. At 40mph the vehicle will move 9 feet forward in .15 seconds, about 1/2 it's length, leaving the back half of the vehicle beind the center point. Claiming that the tanks will close to ploint blank range is stupid when they are facing concentrated AT fire. 1,000 yards isn't exactly point blank range. -- "The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents." - H.P.

What about a tripod launched cruise missle with a range of say less then
50km. You would only need one or two people to launch a missile this size, they could hide in a mosque or cave and fire it towards the yankee-imperialist *******s when in visual range (or if they have any intel from outside visual range). You could set the altitude at launch and approx distance to target (ie do not look for target until you have travelled 3km or whatever), this would prevent blue-on-blue - at least enough for them. The target could be acquired using cheap off-the-shelf digital equipment, we now have 5 megapixel digital cameras for less then 500 bucks, any bets on the price in a 2 years? 5 megapixels will pick out humans from kilometres away and convoys even further. Image recognition is not that hard, at least not for what we need. It only has to find a tank or truck, not tell us the make and model. When you have 100,000 missiles it doesnt really matter if only 10% hit targets. For supporting evidence of how far image recognition has come use some OCR software - it does a pretty good job of handwriting now, not bad for a computer. Also look to facial recognition software - the computer has to find faces in large, moving crowds and then find a match in a quick manner. Admittingly it doesnt work very good (doesnt stop silly govt.s thinking about buying it of course) but our system only has to find a face (tank, humvee, grunt). You could also set a target priority at launch to help prevent 300 missiles all going for same tank (ie this batch go for tanks, this batch for grunts and this batch for trucks, etc etc). You would still get overkill but again it doesnt really matter for our hypothetical despotic nation. Another problem raised was flight control for the missile. I dont think this will be an issue since we already have UAVs for less then 20,000k that can fly themselves and CPU power keeps getting higher. Today I saw that yamaha has a fully autonomous helicopter, I am no expert but a helicopter would be more difficult for a computer to fly then a missile no? So there you have it, a missile that can be cached around the country, small and cheap and potentially damaging enough to send the troops home (or at least make the invasion very embarrassing).

However, consider that telling a tank or truck from an empty road is easier than telling a face from another face. Another problem raised was flight control for the missile.

They are reputedly more difficult for a human, at any rate. -- "It's easier to find people online who openly support the KKK than people who openly support the RIAA" -- comment on Wikipedia (Email: , but first subtract 275 and reverse the last two letters). |

Why people think otherwise that is beyond me. Me neither. I can see why some people might think that as a nation we are not too bright or perhaps easily manipulated, but we certainly seem to be willing to fight. 2) There are people to this day who think they can make a war too big to fight. America is BIG, it really is BIG, I mean really, really BIG. When America goes to war, it does not gear up production to fight, instead it uses the war to clean out all the old stock it has lying around to make room for new shiny weapons that it will make later after examining the results of the old weapons. By the way America hate holding onto old stock, it does not matter how little you are, they want to use all thier old stock on you to clean out the inventory. I guess it make the paperwork easyier. 3) There are people to this day who think they can make a war too expensive. America is rich, it probably is the only country where government people say "A billion here, a billion there, soon it starts to add up to real money' and mean it. In other words if you spend a billion dollars making your defense system, America can afford to spend ten billion tearing it down. Ditto, if you spent 10 billion. Tell me something, do you like throwing the nation's money away? I gather we spent about $60B fighting the Iraq war, and are planning to spend another $80B or so on "reconstruction". "Reconstruction" is apparently not reconstructing very much at the moment (almost no power in Iraq, water shortages, etc. from an article I recently read) - despite a very large budget. Oddly enough, Iraq did a much faster job of reconstruction all by itself without US help after the Gulf war. Go figure. What are we actually getting for our money? Do you think that the US gvt is going to find the mysteriously missing weapons of mass destruction? Apparently you don't want to set any limit into how much money the US will throw away. The recent trend to mindless militarism in the US frankly alarms me. If we were actually getting something from it as a nation, it might be understandable (though not particularly ethical, a sort of "big fish eats little fish might makes right" sort of ethics). But we're not even getting anything from it (as a nation, I mean, I'm sure a few rich people are getting very much richer). |
