I feel like you've invented a brand new war crime. Good job!

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. Random twitter and YouTube comments belong in the Low Hanging Fruit thread.
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 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. These include Social media screenshots with a title punchline / no punchline, recent (after the start of the Ukraine War) reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Low effort thread 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.

Totally non credible, where's the sight?
My favorite thing about this is that the safest person... would be the one the barrel is pointing at.
Is it? How would the physics work here?
I mean, the trigger mechanism could use some foolproofing, but wouldn't the radiation go out the only opening it has?
The demon core's shell isn't shielding, it's reflective and is what causes the fission material to go supercritical. The only shielding on this gun is the lead barrel. Once the two halves are closed, the entire sphere would go supercritical. Importantly, this wouldn't cause an explosion but would instead bathe everything around it in fatal levels of radiation as the sphere rapidly heats up and starts melting. Since the lead barrel is the only shielding, anything directly behind the barrel would receive less (though probably still a fatal amount) of radiation.
Because of the circular hardened barrel pointed at the target, it would be the least likely direction for shrapnel to be thrown when the whole thing fuckin explodes
It would explode generally, and disperse bits of the core all about. Congrats! You have a dirty bomb, and all the physicists in other countries will laugh at you. (See the DPRK tests in the aughts)
This is why we invented the fat man configuration, which then powers the Teller-Ulam configuration in most hydrogen bombs.
Remember that the demon core and reflectors were lab bits used for the development of the atomic bomb configurations. Little Boy was named in the convention of the Tallboy earthquake bomb, and was a gun design that shot the core with enough force to prevent dispersal before complete fission, and Fat Man evenly compressed the core in all directions, again with enough force to prevent dispersal before complete fission.
The demon core wouldn't explode. It just emits a bright light, fatal amounts of radiation, and would melt if kept closed for more than a few moments.
At least that's based on the info I found digging around.
Yeah, those cores will only detonate through a carefully orchestrated implosion explosion that, with the addition of a neutron reflector, triggers the plutonium to undergo fission as the volume it occupies collapses due to the explosive lenses.
Or something like that, I'm not a physicist.
That's the gist of it, to my understanding. The demon core makes fission happen, but slower. Like slowly sprinkling raw sodium into a lake, compared to throwing all 50kg in at once.
I think they are implying that when it is nearly fully enclosed it would go super critical...and kaboom.
No kaboom. The demon core emits radiation and melts if kept closed for too long. The only shielding on the gun is the barrel, which is why being down sight of it would be the "safest" place to be (though not safe enough).
No muzzle flash, just cherenkov radiation in your eyes
Alexa, play Blinded by the Light
And then, three weeks later, boom, dead.
Works everytime, cannot fail.
Ah I see you're a modern Krupp
Early concepts of X-Ray Laser ABM systems developed for the Strategic Defense Initiative worked similar to this, in which an atomic bomb would provide the light to feed a laser directed at enemy ballistic missiles. Since we didn't want to send nukes up into orbit (which would break treaties against OWPs) we'd have to pop them up via a launch vehicle, probably as large as ICBMs themselves. (Wikipedia)
