    Laser tanks are impractical. What if the enemy wears mirrored shades? That laser goes right back and kills you instead. You don’t want your 100 million dollar tank to be taken out by a pair of Ray-Bans.

      The US military has in the past used some large vehicle mounted beam weapons that make your skin burn like all hell, such as the Active Denial System, and I wonder if those could be deflected as well or if they’re the part of the spectrum that needs more sophisticated shielding?

        Those aren’t lasers, they’re millimeter-wave radio beams.

        Yes, they can be deflected pretty easily, but you’ll need metal shield that’s big enough to entirely hide behind.

    I only we had something we could fire that do almost the same arc as that. That would be ballin’! So I’d call it ballistics

      That would work if the earth wasn’t flat. As it is, you need to transport the artillery below their position and shoot them from there. Like Ender shooting through the ice clouds.

      …the color of a blaster bolt (character-scale or starship scale) is determined by the quality of the gas used in it - higher quality gives you green, lower quality gives you red. The Rebellion didn’t have access to the highest quality gas, and had to make do with the lower quality ammunition.

      Huh, I guess I wondered but never looked it up until now.

        I mean, that’s how it was retconned, but it was originally just so viewers could tell if it was the good guys or bad guys shooting. Just like there were only supposed to be blue (good guys) and red (bad guys) lightsabers. As the Star Wars universe and lore expanded, things got retconned and added/changed/removed, and it’s still happening with the new stuff that comes out. Isn’t world-shaping neat?

    If you fire a laser against a mirror, it bounces but raises the heat of the mirror so you end up melting the mirror and destroying the drone.

      I may risk being too credible here, but a $80 drone is a lot more expendable than a $40m laser tank. The drone can be considered a consumable. Hell, mark the drones down as ammo.

      Depending on how long you do it, how powerful the laser, and how quickly it can cool off at the same time.

      And like the other guy said, you can make really good mirrors if you only care about one wavelength.

        In all seriousness, wavelength-specific dielectric mirrors can approach six nines of reflectivity.

        The hard part is hitting the mirror instead of the drone.

            Yeah I guess you can’t pulse-ablate a mirror made of plastic.

            Though it invites a backup strategy of spraying your enemies with molten drone.

    Mirrors melt and break when hit with a laser of more than “pretty lights power”.

      Inverse square law is just a geometric limitation, focus your lasers more, problem solved.

    This was a real concept for the anti-ICMB 747. The idea was to loiter it outside air defense range and then send drones in as reflectors to target the lasers much closer to the threat.

      Interesting! Yeah, I think in the right atmospheric conditions this could absolutely work.

      Why it’s NCD, as drawn, is that shells already exist and do exactly this when fired on an indirect arc.

    Alternately, polish every car window facing east.

      There’s a building in central London that melted a car. Solar laser, so SEO friendly, so on fleek.
