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.

Isn’t gps NA specific? What good would jamming do?
GPS is a product of the US military; its usefulness to them would be limited if it were North America only, since they mostly wanted it to tell where they were, wherever they happened to be in the world that they had no knowledge of but were actively fuckin' with.
GPS is equally available to civilians in Freedomland as it is to civilians wherever else in the globe. They used to arbitrarily fuck up the signal resolution for the non-military version, until they realized that all they were doing was (a) mildly inconveniencing tech companies who had go through the rite of passage of assigning a single junior programmer to determine how to mostly undo their resolution-fucking-with which wasn't that challenging (b) motivating every other country to develop their own GPS equivalents.
By the time they just let everyone have real GPS, people had cottoned on to the idea that maybe putting your navigation under the whims of the US military wasn't a great idea, and had gone to the pretty significant expense of developing their own. So now there's a bunch of them, and you can pretty much choose whichever one pleases you. But with the exception of NavIC, they're all available all over the world.
wait gps is unscrambled niw? then why is it still so inaccurate?
This page explains the reasons and seems pretty credible (and also gives a date for the descrambling; it was fixed as of May 2000).
