      This will come in really handy among the hills of Afghanistan and the narrow streets of Bagdhad. Imagine being able to pinpoint terrorists, find weapon caches and occupy territory with these weapons- why they are just as useful in these scenarios as they are against the imaginary massive army of mechanized forces for which they might have been of some use. Just the thing to run up the deficit and a great trade off compared to say, more active duty end strength or veteran education programs.

        I'm guess you're being sarcastic, but taking out incoming mortar, artillery, and rockets really would be a boon in most forseeable conflicts including Iraq. For instance [washingtonpost.com]: "BAGHDAD, July 10 -- More than two dozen mortar shells pounded the Green Zone on Tuesday, killing three people, including a U.S. military member, and injuring 18, among them five Americans, U.S. officials said."

            the idea is to pump so much energy in it via light energy that it heats up and either causes the internal explosives to detonate in the air so that it isn't a threat or to cause the shell to heat up to the point where it fractures and breaks apart and is no longer a threat or to cause the caseing to vaporise and again.. not be a threat

            it isn't that hard to do .. jsut requires extreamly good aim and tracking and a massive power source..
        • I'm no expert on the technology involved, but I'm guessing that if you know that incoming rockets/mortar are in the air with enough time to get the trucks in position and shoot them down with a laser, you also have enough time to get out of the way, and you probably already have a bead on the source of the fire. Any laser-equipped trucks with an actual ability to shoot down incoming missiles and objects will of course become the first target of any such attacks. I'm not saying this tech is useless, but I'

      The adult in me says ... Guns of destruction are bad.

      No, that's the adolescent in you that says that. It wants to stop killing, hurting, and threatening, and goes after a tool that is capable of such things.

      But once you've had enough time and thought to understand the unintended consequences of the simple "solution" - disarming the law-abiding - you'll reach the adult understanding that self-defense requires force, and that a credible threat of retaliatory force produces a net reduction in killing, hurting, and threatening.

      "Mutual Assured Destruction" works at both the wholesale level (having prevented an all-out nuclear war for over half a century now) and the retail level (convincing crooks they want to leave you alone and either go after an easier victim or find a new line of work.)

      Second-order effects often swamp first-order effects, producing (initially) counter-intuitive results. Part of growing up is learning which situations are like that, and what the useful counter-intuitive solutions are. (To people with less experience this is often mistaken for wisdom, cynicism, or evil.)

      Unfortunately there is a significant fraction of the population that either never DOES grow up or never learns some important lessons about rare, but deadly, situations.

    I wonder how much power it takes to run and if it can target multiple incoming threats at once. It would be awesome if it could take on say 5 or 8 incoming mortars at the same time. Even better would be knocking out a barrage of RPG's. I guess the final implementation would be zapping bullets out of thin air which at that point you'd have a "shield" like in sci-fi.

      1 truck, one laser, one threat at a time. Ability to handle multiple projectiles would be to either have multiple trucks or deal with the attack sequentially. IE it takes 3 seconds to deal with one projectile while the set is targetable for 30.

      Knocking out a barrage of RPG fire is unlikely, RPGs are actually very short ranged, pretty much strickly line of sight, sub 300 meters. There's several different technologies designed to help deal with RPG fire. As for plain bullets, the old technology still work

      Rail guns are what the navy is going to use to replace cruise missiles (which replaced heavy ship artillery). Lots of advantages there -- about the same range and precision and destructive power as a cruise missile, but at a fraction of the cost. Plus has a huge advantage over both cruise missiles and conventional artillery shells in that the ammunition won't explode if the ship gets hit -- though I imagine the gigantic capacitors needed to fire the gun may blow up if charged up and hit, though that'd only be one shot's worth of energy rather than the ships whole payload. Rail guns have a bright future, as long as they can figure out how to keep the gun from destroying itself every shot.

      Lasers so far are mostly being considered for defensive roles to shoot missiles and artillery down. This is a good role for lasers, since first hitting the target at the speed of light is good when you're trying to hit a small fast moving target, and second because the energy needed to destroy a warhead isn't that large.

      Two awesome future technologies, two roles. It's a good time to be a geek. :)

Yes, you can use lasers for terminal guidance but that requires something to paint the target (hard to do when the target is in hostile territory. Being ballistic, it's also vulnerable to the laser defense systems being discussed here. The launch profile for a rail gun also limits the guidance package you can fit. A cruise missile

This thing is meant to defend against short-ranged mortars, rockets, and artillery. So it has to be sited up near the sharp end. Something more rugged and more mobile is needed.
