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.

When I read this news this morning I thought it was like a Vespa style scooter. Was it really an electric scooter like this? That makes it even funnier.
Edit- I read the news before the footage was released, and saw this post before the posts with the footage. Lul. Also holy fuck that was a big explosion from such a tiny boi.
> that was a big explosion from such a tiny boi.
Remember, the nuclear material which was dropped on Hiroshima and Nagasaki was about the size of a cricket ball.
The explosion could have been a little bigger!
Hiroshima's bomb was Little Boy, which contained 64 kg of uranium, which at 19.1 g/cm^3 would be about 3.3 liters, significantly larger than a cricket ball.
But Nagasaki's Fat Man used about 6.2 kg of plutonium, which has roughly the same density as uranium, although the implosion mechanism to initiate the chain reaction compressed it to about half the volume. So that's closer to a cricket ball.
But also to add even more nuance, the plutonium in Fat Man used a uranium tamper to reflect neutrons, and estimates are that about 30% of the explosion yield was due to fission of the uranium too. So it's hard to really draw the line on what was or wasn't the "explosive" in that bomb.
Y'know, I've done a lot of "hobby research" into nuclear weapons, but never really did the math on the degree to which the pit was compressed. Just on an intuitive level, it's already a bit difficult to fathom solids compressing, but not unreasonable to imagine. However, in my head it was like, a couple percent at most. Forcing a solid ball of insanely dense metal into a space half of what it originally was just blows my mind even more.
