  Good on you for telling north Korea to get it's shit together.
context: They better shoot down those drones. >
  
  Ukrainians use this little signal shooter to disable a UAV's rotors and bring it down to the ground. How does South Korea not have this tech yet? >
  
  Those signal shooters only work against radio controleld drones. If they have a preprogrammed flightpath they [edit:BurnoutEyes has a point] ~~don't~~ might not do anything. Edit: Depends on the jamming systen of SK and drone navigation of NK. 
  If those were small propelor spy drones, then wasting patriot missles on them is an absolute waste.
  Until we know what kind of drones North Korea used, it's hard to say what South Korea could to better. >
  
  
  If they have a preprogrammed flightpath they don't do anything.
  
  Some of them try to interfere with the crystal oscillators and clock distribution networks. >
  
  How do they do this? >
  
  They blast a bunch of directional RF at it tuned to different harmonics of the oscillator in an attempt to mess up the PLL. The higher frequencies of the harmonics have shorter wavelengths and can get into PCB traces. It only takes a little decoherence to fuck it all up.
  They decided to violate Part 15 of the FCC rules really hard. >
  
  It recquires atleast 30 metric buttloads of power to actually cause harm to a physical component from a few hundred meters
  Theres a reason wireless charging is shite even from a few milimeters away its only 70% as effective as just having wires >
  
  You don't need to burn out the transistor, you only need to cause enough ripple in clock lines to cause them to stay open or closed a bit longer than they should. Digital electronics require carefully synchronized clock distribution networks.
  The principle you're referring to is the inverse square law by the way. Funny enough in radar the effect gets applied a second time to the return path, so it's way worse for signal strength than you'd think, yet transistors pick those up still. Digital electronics are really sensitive. >
  
  Inverse-square law 
  
  In science, an inverse-square law is any scientific law stating that a specified physical quantity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space. Radar energy expands during both the signal transmission and the reflected return, so the inverse square for both paths means that the radar will receive energy according to the inverse fourth power of the range.

  This is the best tl;dr I could make, original reduced by 63%. (I'm a bot)
  
  
  Lee said the South Korean military conducted a reconnaissance mission after the drones entered its airspace, with some assets crossing into North Korean territory and filming its military installations.
  The last time a North Korean drone entered South Korean airspace was five years ago, according to the South Korean military.
  North Korea has aggressively ramped up its missile tests this year, firing missiles on 36 separate days, the highest annual tally since Kim Jong Un took power in 2012, according to CNN. On Friday, South Korea said North Korea launched two short-range ballistic missiles, according to CNN..

  One drone traveled as far as the northern part of Seoul, South Korea's capital, about an hour's drive from the border
  
  The northern parts of Seoul proper (not even looking at Goyang or Yangju that are part of the Seoul metro region), is not even 20 miles from the border... Traffic might be a bitch to deal with, but damn who frames it like that? Even a DJI drone can cross that distance in like 5-10 minutes... >
  
  I mean, they said drive whereas the drones were flying. But also 20 miles shouldn't be more than like a 30 minute drive assuming the speed limit slows as you start getting into an urban area >
  
  You've obviously never driven in Korea. 20 miles SHOULD only be a 30min drive, bit it isn't there. An hour sounds about right. >
  
  Gonna go out on a limb and say 99% of Reddit has never driven in Korea but go ahead and make traffic sound like a foreign concept >
  
  Exactly what someone who never drove in Korea would say >
  
  Are we gatekeeping traffic? >

  They've found a niche and filled it. >
  
  Why warnings? They’re drones just do it >
  
  They kept missing, and crashed their own plane, so saying they were "warning shots" lets them preserve some dignity >
  
  Ouch… that’s a sad win for NK. Invaded their airspace to provoke a response AND got a crashed plane out of it. >
  
  NK propaganda doesn't even have to try to stretch that truth... >
  
  "We took out a southern aircraft with an unarmed recon drone! We are victorious!" >
  
  Humans trying so damn hard to start a world war >
  
  Autocracy gonna autocracy >
  
  Why fire a "warning shot" at an unmanned drone? Just shoot the damn thing. If politically necessary, just say you honestly meant to miss it. >
  
  They did miss. That's why they're being called "warning shots." >
  
  North Korea has drones now? I thought they were on the 60's >
  
  Their buddies, china and russia >
  
  I think Russia might need them for themselves at the moment >
  
  Doesn’t mean that someone from Russia didn’t want to smuggle some to their neighbors c: >
  
  The ol don't forget about me from North Korea >
  
  If they are drones, I fail to see the need for warning shots when what is essentially a munition is "fired" into your territory. >
  
  It's likely a Chinese drone resistant to electronic warfare. China and Russia are testing their tech against nato installations to probe for weaknesses. >
  
  Russia had to pay for those artillery shells somehow. >
  
  That anti drone gun looking like a ghostbusters proton pack >
  
  This pic is wild.  Somebody needs to tell SK that COD isn’t real >
  
  This thread filled up with North Korean warehouse bots faster than the drones made it to Seoul. >
  
  My thoughts exactly. An awful lot of folks seeming to support North Korea in the comments… >
  
  North Korea is getting a little jealous that Russia is getting all the attention. >
  
  Dude in the thumbnail waited 5 years for his time to shine >
  
  NK is just mad no one is talking about them. >
  
  When I was there in 03, I was out drinking with Russian girls when N Korean and S had a small naval battle were 3 Saylors were killed.   Thank God I was drunk and didn't care or I wouldn't have slept that night.  I was at a base pretty close to the border.  We joked we were just a speed bump for the airforce to come take care of N Korea.  Not the ones in Korea.   They would have been whipped out even before they hit us.   Our first hitters would come from Japan.    20 years later,  I kept eye on issues over there thinking If that didn't start ww3, nothing would.   Most importantly, I learned to not care and to live my life finding peace and get my soul ready for the inevitable.  It comes for all of us. >
  
  Warning shots and bad marksmanship look surprisingly similar. >
  
  Brooo its really ww3 out here >
  
  This is how they start. >
  
  NK has drones?  Are they more than the quad copters people buy online? >
  
  Anti-drone gun?!
  Off to Google >
  
  Sure let's have another armed conflict. Might as well. >
  
  NK has drones? Are they cameras with balloons strapped to them? >
  
  I assume it’s because North Korea is desperately upping weapon production in order to sell to Russia? >
  
  North Korea about to find out their military is faaaaaaar less capable than the Russian army. >
  
  Oh no 👀 >
  
  I hope those warning shots accidentally connected due to the drones erratic movement and knocked them out of the sky. >
  
  Tbh I bet you dollars to donuts that South Korea would kick North Korea’s shit in if they did anything. >
  
  Pleeeeease stop fucking reporting nk shit I'm sick of it. They're literally never gonna do anything so everyone needs to chill out >
  
  Inching ever closer to WW3 everyday. >
  
  Hi, I am North Korea, I have one of the largest standing armies in the world, but, my population is starving, my military equipment is decades old, I have pissed off all of my neighbors and my only friend (China) thinks I'm a disobedient little shit a d perhaps not worth the effort. 
  So to compensate I will laugh missiles and drones over my neighbours because......reasons.
  Oh, and also I rewrite history to a ridiculous degree, for example, did you know the Korean war started when the USA invade my land and not when I invaded South Korea? >
  
  What kind of drones are these? Should we be worried?
  I know this is NK but still, I didnt expect them to have DRONES. >
  
  Dude I’m just a regular guy with a toy drone. Of course their military has drones >
  
  This is embarrassing and they should get their act together asap
