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.

What are the most common ones though? Jammers in UHF are shorter range than the VHF jammers, and so these would help with the network.
It also doesn't do you any good if you're trying to attack the tank and all you have is 1GHz+ drones. Equipment isn't made to deal with anything and everything, after all the radar isn't obsolete since it can't defend against an artillery shell.
433 MHz, 915 MHz and the "wi-fi ones", 2.4 Ghz and 5.8 GHz are the most frequent in off the shelf components
433 MHz is banned in Europe but allowed in the US.
915 MHz is banned in the US, but allowed in Europe.
The wi-fi bands (they don't go by that name, it's just most commonly known for that specific use) are allowed everywhere per international convention.
I'm just saying, they could have selected the jammers better.
there's also 3.4GHz band, rarely used, could collide with some radars
433MHz could interfere with some 70cm band radios, depending on how badly are all these baofengs misused
Of course, if you make your own drones from scratch, you can make them work on any part of spectrum, including what is normally advised against. There are tradeoffs to be done, but not all rules of electromagnetic compliance will be adhered to in wartime
I think if their jamming goes up to 3 GHz, the sidebands of the jammer might affect at 3.4 GHz too, but yeah, there is also that one.
The problem with making your own RF systems is that Ukraine would require a steady supply of RF components, which might be hard to secure in war time over off the shelf, which probably have stocked supply lines in most places, through hobbyists stores.
