A community for your defence shitposting needs

Rules

1. Be niceDo 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.

You got me considering an unshielded, focused/directed microwave beam. And then my dumbass realized I had reinvented the MASER (Microwave Amplification by Stimulated Emission of Radiation).

So, why aren't defenders using those?

Its generally always the same problem with any kind of laser, maser, whatever variant of a beam of intense energy of some frequency:

They require stupendous amounts of energy, and if your platform is mobile, that means batteries.

Batteries that are big, heavy, and tend to immolate like a burning cybertruck at fucking 1800 F or what not if structurally comprimised.

We still have yet to get reliable, hardy, high energy dense batteries to a point where it doesn't either massively weigh down your platform, or require some absurdly expensive production process for a more advanced battery, because we only know how to make 'can test its properties in a lab' volumes, not 'actually industrial scale mass manufacturing' levels.

They make kinda sense on say, a naval mounted rail gun... they do not downscale to truck, tank, infantry scale.

Like you could maybe make a giant rail gun tank with current tech. Maybe.

Problem is it would be ~70% battery by mass, weigh ~250 tons, be able to fire maybe... 5, 10 times? and if basically anything pens the armor, you now have an inferno that will burn for 12 to 24 hours, likely into a slag that actually burns or digs a hole a foot or two into the ground, roughly shaped like its foot print.

i think masers sort of suck. as when strong enough to be useful they create plasma and plasma scatters the maser.

although I read that quite a while back, so maybe progress has changed that
