    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.

        https://www.military.com/daily-news/2024/04/24/army-has-officially-deployed-laser-weapons-overseas-combat-enemy-drones.html

        The Army has officially deployed a pair of high-energy lasers overseas to blast incoming enemy drones out of the sky, the service recently confirmed, marking a major milestone for the U.S. military’s ongoing development of futuristic directed-energy weapons.

        The 20-kilowatt Palletized High Energy Laser, or P-HEL, “is currently deployed to support the Army’s mission” in an undisclosed location abroad, a spokesman for the service’s Rapid Capabilities and Critical Technologies Office, which manages its directed-energy portfolio, told Military.com.

        I think the bigger concern is enemy UAVs wearing shades.

      The moment those mirrors stop being perfectly shiny they begin thermal collapse. Which is the real reason mirrors exposed to the atmosphere can’t be used as targeting optics.

      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.

      …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.

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

    This is also how you check if your ass is clean.

    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.

    Or… skip a step. Line of sight is irrelevant if your aircraft is already exploding!

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

A community for your defence shitposting needs

Rules

1. Be nice

Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.

2. Explain incorrect defense articles and takes

If you want to post a non-credible take, it must be from a “credible” source (news article, politician, or military leader) and must have a comment laying out exactly why it’s non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.

3. Content must be relevant

Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.

4. No racism / hatespeech

No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.

5. No politics

We don’t care if you’re Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.

6. No seriousposting

We don’t want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.

7. No classified material

Classified ‘western’ information is off limits regardless of how “open source” and “easy to find” it is.

8. Source artwork

If you use somebody’s art in your post or as your post, the OP must provide a direct link to the art’s source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.

9. No low-effort posts

No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.

10. Don't get us banned

No brigading or harassing other communities. Do not post memes with a “haha people that I hate died… haha” punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.

11. No misinformation

NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don’t be an idiot.
