Leaked video of Russian tankers utilizing the new cope cones

What movie is this? Looks familiar

What a great way to advertise your location

New control system.

Have a suicide drone head straight for the interference signal, HARM style.

Next: Ukraine starts using 899 and 3001 mhz drones

[-] Rand0mA@lemmy.world 6 points 11 months ago

Im pretty sure the control amd video feeds for my drone is switchable between 2..4ghz and 5.8ghz.. Range of 7km with uprated antennas, and its just an old dji phantom. Nothing fancy. Instantly doesnt give a shit about this tank tech.

[-] Rand0mA@lemmy.world 3 points 11 months ago

Honestly, I never tested that distance. I reached about 5km piloting from a hill, with a clear line of sight, video (on 2.4ghz) and the control (on 5.7ghz) with good signal still for both feeds.

I'd be halarious if these photos were taken from a Ukraine drone while Russians were operating the tank...also wouldn't surprise me

[-] NeuronautML@lemmy.ml 19 points 11 months ago* (last edited 11 months ago)

They are terrible anti drone nipples then, considering you can easily find off the shelf drone RF antennas at the 400 MHz range easily, which is below 900 MHz. You can also easily find on the 5.8 GHz range.

Must be why drone attacks are so effective against Russia.

[-] skillissuer@discuss.tchncs.de 3 points 11 months ago

400MHz? you mean 430MHz-ish, which is near 70cm band?

i heard that Ukrainians are using 900MHz band for long range drones, that puts it near ISM band also used for LoRa and some other applications like this

[-] Estiar@sh.itjust.works 1 points 11 months ago

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.

[-] NeuronautML@lemmy.ml 4 points 11 months ago* (last edited 11 months ago)

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.

[-] skillissuer@discuss.tchncs.de 4 points 11 months ago* (last edited 11 months ago)

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

[-] NeuronautML@lemmy.ml 1 points 11 months ago

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.

"Dammit man, it's like tits on a Russian tank" was not a phrase I was expecting to learn had some veracity this week

[-] ProfessorProteus@lemmy.world 4 points 11 months ago

Oh you know there's some anime out there where they depict tanks as girls. They've already done it with warships, right?

[-] Schiffsmaedchenjunge@feddit.de 2 points 11 months ago

I know of warships as girls, guns as girls and fighter planes as girls but I'm not aware of tanks as girls.

[-] kittyjynx@lemmy.world 2 points 11 months ago

The youtuber Cone of Arc uses a tank girl avatar so there is at least one out there.

[-] Astronautical@sh.itjust.works 1 points 11 months ago

There is a series called "Girls Und Panzer" I think

[-] pinkwerdo@lemmy.world 1 points 11 months ago

But the tanks aren't girls.

If remote control doesn’t work anymore it’s time to roll out the fully automated AI killer drones that hunt down anything that moves. Nothing can go wrong, surely nothing can go wrong…

[-] Estiar@sh.itjust.works 1 points 11 months ago

Could be useful against those drone dropped grenades. Especially at shorter range. Actually a good idea, though they still look funny.

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. Random twitter and YouTube comments belong in the Low Hanging Fruit thread.

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 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. These include Social media screenshots with a title punchline / no punchline, recent (after the start of the Ukraine War) reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Low effort thread 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.
