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.

ok so the giant battery is in the tank, guess how big a cable would have to be? You're not putting that on a quad
edit: it's also impractical as hell to tether drones when most roads get netting installed over them, just saying
edit2: why not just put the laser on the tank? fry the drones around you directly instead of hoping you cut the comms in the fiber optic lines
not very
I can show you a chunky 500W cable for a pc power supply, would be just as relevant. Look up cables of actual laser power supplies, they're big and relatively dense, and we're talking about tethering a quad, it's not gonna fly well with that dangling.
This man has never heard of ohm’s law
This ohm's law?
Not a man but I take your point, consider that this drone and the cable is gonna get peppered like crazy. Plus you don't want it tangling up
Apologies, I had meant “man” as person but I recognize that usage is dated. No gender assumption was intended.
the tank has a giant gas turbine why do you need a battery
Find me a tank with a 5kW turbine
edit: i misread the units yall don't stone me to death
The battery isn’t the issue they were talking about. They meant “so instead of batteries on the quad you’re powering it from the tank.”
The gas turbine in an Abrams produces 1100 kW
https://en.wikipedia.org/wiki/Avco-Lycoming_AGT1500
If you mean a dedicated turbine producing 5kW of electricity then it already has an accessory gearbox drawing up to 75kW out of the 1100 for peripherals. I doubt they're currently generating (pun intended) huge amounts of electricity, but the drive is there for exactly this sort of purpose.
A 5kW alternator seems to be about $700 on ebay
https://www.ebay.com/itm/146849456677
If a reasonably skilled engineer cant fit that there's something wrong
My bad, i misread the units
It wouldn’t have to run at full power all the time, just when actively defending against a drone. There are lots of other harder to solve issues.
Ok and? Still needs batteries and cables to withstand peak power, still needs to be tethered somehow, still needs another crew member constantly flying it. Not to mention being this close to combat and to the ground, you better have some insanely good lens protectors or that laser is gonna be out of commission after any shrapnel lodges itself in.
Completely made up idea to counter this made up idea, but if you're putting it on armor - a 12 gauge turret sounds so much easier. Doesn't need a shitload of power, can put it onto a generic stand/turret base, targeting is easier and you're guaranteed to ruin the enemy drone's life
The laser could be on the tank with a mirror on the drone
