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.

What about barrel cooling? Getting rid of heat is a major challenge in a vacuum.

[–] empireOfLove2@lemmy.dbzer0.com 23 points 4 weeks ago (4 children)

That's why I say you need to provide a closed liquid coolant loop around the barrel that would ve integrated with your ship's heat management system, to replace the air cooling of the barrel.

https://en.wikipedia.org/wiki/M2_Browning

The development of the M1921 water-cooled machine gun which led to the M2, meant that the initial M2s were, in fact, water-cooled. These weapons were designated Browning Machine Gun, Cal. .50, M2, Water-Cooled, Flexible.

space ready since 1933! We really were ahead of our time!

Will the blood of my enemies suffice?

[–] Glemek@lemmy.world 3 points 3 weeks ago

Only if they are cold blooded

[–] empireOfLove2@lemmy.dbzer0.com 3 points 3 weeks ago (1 children)

A little thick, but good enough.

[–] verity_kindle@sh.itjust.works 4 points 3 weeks ago (1 children)

Sugar is almost as corrosive as salt, so please make sure your enemies are on a sugar- free,salt-free diet, i.e., dying, saving you the trouble.

[–] empireOfLove2@lemmy.dbzer0.com 2 points 3 weeks ago

Way ahead of you there!

[–] mojofrododojo@lemmy.world 9 points 3 weeks ago

to replace the air cooling of the barrel.

radiators work in space, just not as efficiently. fill 'em with ammonia, put more fins on for larger surface area, I'm sure the M2 could be adapted.

no because without gravity to pull them back down your bullets would just keep going up and up and over whatever you're trying to hit

[–] borari@lemmy.dbzer0.com 6 points 3 weeks ago (1 children)

Bullets don’t inherently go up when fired, they go straight out of the barrel, the barrel is just inclined because of the sight alignment. You just realign the sights, this isn’t a difficult problem.

yeah because of gravity

get rid of all the gravity and they'll go straight up

don't come crying to me when your bullets go up so much they do a full loopdeloop and shoot you in the back of your head because you tried to fire them on the moon where there's no gravity

i know we're on noncredibledefense but please take this seriously

[–] NigelSimmons@startrek.website 1 points 3 weeks ago

But actually, if you had no gravity acting to change the velocity vector, the bullet would continue in a straight line. If you shot at the horizon it would be like drawing a straight line tangent to a circle. The bullet's not going to end up going in the shooters azimuthal direction, but it sure is going to gain altitude as the curvature of the body peels down way away from the straight line it's flying,

[–] Glemek@lemmy.world 4 points 3 weeks ago (1 children)

I bet all of them make a loud wooshing noise as they head straight up from the moon to earth.

[–] switchboard_pete@fedia.io 4 points 3 weeks ago

you seem like an expert in moon warfare

[–] switchboard_pete@fedia.io 5 points 4 weeks ago

just blow on it
