Claiming that the tanks will close to ploint blank range is stupid when they are facing concentrated AT fire. I'm also not sure he understood the potential of the Otto-76 to shoot down smart munitions. 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. ANTIcarrot. |

That's the real obstacle-- not in coming up with a magic weapons design, but in producing the people who can design it, and more importantly, *build* it, which requires an educated and at least reasonably prosperous nation to build it. Again, China is probably one of the most capable of the 2-3rd teir nations, and they needed foreign help for their orbital rocket shot. I'm not mocking them-- it was a tremendous achievement, especially when you consider everything they've had to overcome in the 20th century, but the fact of the matter was that they still needed some outside knowledge/assistance for it. The same thing goes double for any of these little countries, most of whom have smaller R&D budgets any european nation. should probably be asked...which countries can do it, do you think, Charles? |

And what makes the think that the radar put there to let the drivers dodge incoming tank-fire cannot detect incomming cluster-bombs? So you detect 200 inbound cluster munitions 3 seconds before they hit, beyond a quick prayer to the deity of your choice how is that of material advantage ? By the way I've yet to see the tank that can outrun an APDS round so quite what you mean by dodging incoming AT fire is a mystery. I never said the radar was for guidence; it's there so they can see and dodge incomming tank-rounds and other munitions.. How do you dodge a round doing greater than Mach 2 ? I must have missed that detail somewhere You can use any missilbe for the SUV, and you can manouver whilst firing. During this period the wire is being pulled out the tube at 300mps at minimum, a few mps to either side is not going to break it. There are also fire-and-forget missile systems. 76mm AA tanks have been developed (although none are in service as far as I know-- the Italians evidently weren't able to sell them), but they have the simple problem of being big enough to be killed from far out side the 76mm range-- you're going to have B2's and B1's dropping LCAS GPS guided weapons, and all sorts of other wonderful stuff from quite far out of range, cued in by UAVs which the Air force doesn't mind losing at all. US army next-gen guided-bombs are essentuially UAVs with 90% explosive filling. They are big and will show up on radar. At this point the gun turns and fires at the bomb/missile before it gets close enough to do damage. How many AFV's have guns with sufficient elevation and slew range to accomplish this feat ? Hint its a SHORT list rest of nonsense snipped Keith |

Which really doesn't buy you much in the way of security. DS-SS merely makes it easier for the receivers to do ranging functions. You're missing the forest for the trees - or maybe you just like to argue? :-) I'm going to give a reference of my own: http://arxiv.org/pdf/gr-qc/9508043 for an overview of a more theoretical and high-level approach as to how GPS works, and to support the following statements I'm going to make as to how GPS works. The very basic principles of GPS are that are it is a bunch of orbiting clocks, all of which (in the simplest model) transmit their own proper time. An observer on the ground, at a fixed location, knows what the proper time on the satellite must have been when it was sent, when he recieves the signal, because he knows (or can directly observe) the satellites orbit. Therfore, ultimately, an approach based on encryption is going to boil down to encrypting something that everybody already knows or can figure out, which is not going to be terribly secure. Spread spectrum tecniques are really crucial to making this system have the level of security it actually does. |

To dodge a tank round all you need do is side-step half the width of your vehicle. To dodge a tank round while driving an SUV, you need to side-step the full soft-target kill radius of a 120mm HEAT-MP round. Unless the Brits are in the game, in which case it's 120mm HESH.

Just to give some figures: GPS will give you 5 to 30 meters accuracy (as long as the US lets you have it). Galileo will give you about the same accuracy. I suppose the US can jam both. I'd guess if they could not, they would not have increased the accuracy publicly available and would make much more of a fuss about Galileo. I doubt that US can jam Galileo just by turning a switch as it it with GPS. But they probably will develop some jamming feature against the Galileos signals. I heared that turning back on selective availability is not much of an option anymore because the economic aplications that depend on it are too valuable to lose and that the SA cannot be targeted in a small enough area.

... Denying the other guy use of GPS doesn't prevent the US military from using it. However the cost to non-military users might very well be the desired effect of the opponent. -------------------------------------- Carl Alex Friis Nielsen Love Me - take me as I think I am |
