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.

I really hope the western allies have a plan for countering drones in the pipeline, otherwise the next time we fight an insurgency will be a bloodbath.

As someone who’s been following this fairly closely since the Syrians started toying with it, and the Ukrainians threw it into hyperdrive… There’s no good counter when drones are cheap to make and can be programmed to run on a flight course:

  • Jamming has to fight inverse square so the radius is trash (and kills a lot of useful civil RF ranges like WiFi). Something like 200 meters is a strong system currently, and power needs ramp up fast.
  • ‘Kinetic hard kill’ like traditional air defense is way too expensive per shot, plus there’s issues with UXO, debris, and limited launching platforms. Legacy air defenses like Tunguska or FlakPanzer with programmable airburst rounds work best, but at very short range and make a lot of secondary fragments by design. Taking the guns out, interceptor missiles start at five figures.
  • Laser systems have a lot of promise with none of the explosive downsides whilst being cheaper per shot, but range isn’t great - you’re focusing energy to physically melt the target, and all light suffers from diffraction. It is better than jamming, but far too close for comfort.

That assumes you know the drone is coming, mind you. Piston-engine flying wings aren’t silent, but they are generally made of polymers/laminates that are hard to detect via radar. Thermal cameras and acoustic sensors so far are the best early warning systems, but radar is still a huge help.

And then there’s FPV and quadcopters. While a larger munition like Shaheed can be under $10k, even the more advanced FPV/quads with night vision (or even thermal) cameras frequently run under $1,000, up to a few thousand. Air dropped explosives have been fundamental in changing the course of the civil war in Myanmar for the rebels, it’s like having a budget Air Force and spy satellites on call.

Why not just use a big shotgun for the smaller stuff, skeet shooting style? I dunno how to really deal with much larger drones, but a shotgun should be able to deal with most human sized drone targets pretty easily

What about a shotgun shell but each pellet is crimped around the midpoint of a bundle of carbon fibers
