NonCredibleDefense
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.

Their rocket exhaust as they're being fired would slow the planes down, rather than providing a boost
For the same reason, cars have exhaust on the rear so that they can go much faster forward than backward
Edit: /s since you apparently need it after every joke. I know that missiles aren't really fired, they detach and then propel themselves. Also, anyone who's ever idled their car on a flat surface knows that the exhaust thrust cannot even overcome rolling resistance.
Ackshually they do this, not with cars but, with WW2 era prop planes.
The Spitfire for example:
From Wikipedia
lol what?
Rockets aren’t attached to the plane when they launch. They release then fire there rockets. It might be near instantaneous but missile thrust has no bearing on an airplane.
The exhaust doesn't propel a car forward
I'm going to start a meme crackpot theory.
Torque doesn't exist.
Cars move because of the exhaust gasses.
"What about trucks with an exhaust that points up?" I hear you ask, well why are they always bent over at the top to point backwards?
Tractors that have an exhaust on the top use it to keep the tractor on the ground, otherwise the forces of dragging things would cause the tractor to float off the ground. But the exhaust is pointed backwards slightly, other wise it wouldn't move. The small backwards pointing force explains why tractors are so slow.
Electric cars are CGI, and part of the conspiracy to hide the fact that torque doesn't exist.
My god, you're onto something here. That must also be why we evolved with backward facing asses, to ease our walks when we fart. Ventilated seats in your car? They help channel your farts to add nitro boost to your car's exhaust.
Fucking hell, the air vents in the dashboard are all blowing backwards against the direction of travel, too. We been living a lie.
And the radiator at the front? Actually for extra speed.
That's all a turbo is. It's just a fan in the exhaust pipe adding more speed.
And superchargers need a big air scoop due to the amount of air it pushes out the back.
This is even better than birds aren't real. Which is true also.
Ah so the cyber truck just never got an up close model made
Yeah for some reason they locked the model detail at some hilariously long draw distance so it only has like 15 polys
I think you've created the sovereign motors movement.
I forgot you need "/s" after every joke, even in joke communities. It is a reference to this greentext:
Let's give anon the benefit of the doubt. Perhaps they're an alien engineer from a planet that only knows rockets, disguised as a teenager to learn about our modes of transportation.
Yes, there is a short film with just about this plot
OK. I didn't know that one.
Oh yeah dummy? Go plug up your exhaust and see if you drive anywhere.
Is that you, Foley?
Is that you, Krtek?
Let's agree on that the effect is of negligible magnitude.
Haven't you seen Batman?
The rockets would need to accelerate in the opposite direction of their initial motion, thus a lot more energy would be needed to reach design velocity. That makes it necessary to carry a lot more fuel for the propellant and thus, the rocket can carry less explosives. For some moment the rocket would also have zero velocity.
On the analogy with the car: The exhaust gases do not carry enough momentum to actually have a nonneglibile effect.
Where do people come up with this nonsense
It's a reference to the greentext I posted in another comment. I know it makes no sense.
