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.

Preface: I know nothing about weapons except "point sharp end away from self".
The article has a video. The video shows drones dropping hand grenades at the jammers. The grenades go off (in a spectacularly disappointing fashion compared to what's depicted in movies, but that's beside the point) but don't seem to damage the jammers in any meaningful way. So, do the videos in fact show effective destruction even if it doesn't look like it?
Post script: I am not a Russian troll. Long live Ukraine! 🇺🇦🖖😎 I am merely not understanding the videos very well.
What you see in movies is bullshit. Any explosion creates a huge fireball and people go flying in every direction. Actual munitions aren't like that. Especially munitions that have to be carried on light little drones. That includes most hand grenades and air-dropped bombs.
I'm concept, an explosion that creates that big fireball puts most of its energy into spreading burning fuel around to create that big fireball. It's visually impressive, but not actually very destructive. In warfare you don't care what it looks like, you want it to be destructive. And the best way to get bang for your buck so to speak with an explosive that has to be lightweight, is with shrapnel. An explosive wrapped in shrapnel is not visually impressive to watch, but it basically sends little bullets flying out in every direction and those bullets are what does the damage.
So consider it this way. If I walk up to the jamming device and shoot it with a pistol, it's not going to be visually impressive. Nothing is going to fly apart and explode in a shower of sparks and flames. The jammer device might not even move at all, it just now has a hole in it. But it is in fact quite thoroughly destroyed because the bullet from my pistol destroyed all of its internal workings.
Same thing is true with the grenade. The hand grenade is designed to be light and effective, so a soldier can carry it without getting weighed down. Thus it is a small explosive wrapped in a lot of shrapnel. Soldier throws it at the enemy, enemy casualties come not from the explosion but from shrapnel wounds. Drop one of those grenades next to a piece of equipment that isn't armored, and it may not even appear to move, but it has been quite thoroughly punctured by shrapnel and is thus destroyed.
Hand grenades produce shrapnel. Having loads of tiny holes in it generally isn't conducive to the functioning of electronic equipment.
