World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Unless they're gps guided, or they can turn their camera away from the laser source in time.
These lower power DEW systems don't target the optics they target propulsion, like the actual rotors themselves. Takes about 1-2 seconds to knock them out on the ISR type drones, maybe a bit longer on the FPV type depending on size.
I'd have thought the rotors would be harder to melt though because of their speed and cooling, but I guess it would work. Could you electroplate the rotors?
I'm sure you could but the more armor you stack on the more you reduce the performance.
GPS wouldn’t be effective at all for drones dropping munitions on infantry moving around on the battlefield, nor on FPV drones trying to fly into moving tanks or other vehicles.
And how do you turn a drone away from an infrared beam of light that would damage the drones optics almost instantly? You’d have to spot the laser system from hundreds of yards away, recognize it’s aimed at your drone, and turn away before the laser is fired. And then what? Just avoid turning your drone back the way you want to go, hoping another strategically positioned laser you didn’t see doesnt fire from a different direction?
You'd need to know where the laser system is, yes. You could do that by having a first done get shot at to reveal the position so the others know where not to look.
Gps would still be effective against stationary targets, but gps jamming would probably be very effective.
