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.

civilian GPS operates at a few fixed frequencies like 1575.42 MHz, 1227.60 MHz, and L5 at 1176.45 MHz (plus 2-3 more; military GPS is a different story). The structure of the GPS data is also fairly well known; all of this is easy to find on the goog.
So you hop on the same frequency start spamming bad GPS data. wrong time stamps, wrong satellite info, etc. with a little effort you can convince a long range missile they're off by 2 miles and should veer left hard.
or you just put a shit ton of noise on the same frequencies and make it so it's forced to use inertial navigation (which isn't very accurate).
Making lots of fake GPS signals, or just pushing lots of power on a GPS frequency.
I have seen countless posts from this community and I still can't tell what its for
On Reddit there are three:
- credibledefence - military nerds analysing military history and present conflicts in a serious way with stringent rules
- lesscredibledefence - fewer rules, casual discussion of mostly current affairs specific to ongoing conflicts
- noncredibledefence - military memes
It's literally just military shitposting.
AFAIK, long shot OSINT.
kinda like how if you talk enough shit, someone will eventually post a restricted document. keeps happening in the Warthunder forums, for example...
Shitposting related to military matters as far as I can tell.
Who wouldn't love https://en.wikipedia.org/wiki/Sensor_fusion ? It's like you get a magical new sensor that's better than the junk you actually have in your hardware.
Man, I gotta rewatch Peep Show, I loved it every time that insane character showed up.
Can't remember his name, yep, been too long, time for a rewatch.
Tell you what, that crack is really moreish!
That episode, with Mark's friend who plays core englaise in the BNP band is one of my favorite episodes of television.
For any other super hans fans, if you've not seen Withnail and I the drug dealer character in that was a major influence on hans.
Super Hans!

Probably just using all the various GPS systems. Unless the Russians are jamming their own system as well.
Given that the Russians took down all of Ukraine's telecoms only to realize that that meant that they couldn't communicate either, and had to therefore use insecure systems does make me think that perhaps they haven't thought it through.
@echodot @IrateAnteater I suspect, despite occasional advances, that on the whole they have thought little of it through. And now their, or rather putines, pride won't let them just say "sorry. We fecked up, just let us back out"
This comment exemplifies 90% of all historical human action.
I think, they do
I also heard hilarious stories of taxi rides costing more than they should because of GPS spoofing around Moscow city centre teleporting cars far off
get datalinked
The missile knows where it is.
Because the missile knows where it isn't
Ah, the elephant sculpting method of navigation.
