By now, many will have seen the video of a Ukrainian drone dropping a small bomb through the sunscreen (!) of a car driven by Russian soldiers. Here's a short thread on how it was done (with thanks to @ian_matveev, on whose thread this is based). /1
For the attack, a modified VOG-17 grenade was used. A fin and a front part, created on a 3D printer, are added. The VOG-17 is a Soviet-era 30x120 mm fragmentation grenade with a claimed effective radius of 7m, covering an area of about 150 m². /2 ImageImageImage
It weighs about 350g (12.3oz) A hobbyist drone like a DJI Phantom 3 is easily capable of carrying one of these. As two grenades were used in this attack, it suggests that a bigger drone was used, two drones were used or the same drone was used to attack twice in succession. /3 Image
The modifications to the grenade are simple, but as the video shows, they enable good aerodynamic performance and high accuracy. /4
The VOG-17 grenade itself contains only 36g (1.2oz) of explosive and can't seriously damage equipment. But there is a lot of such ammunition in Ukraine. It's usually fired from an AG-17 automatic grenade launcher, a Soviet equivalent of the US Mk 19. /5
Low-cost hobbyist drones armed with small modified grenades provide a cheap and effective weapon against individual soldiers. Factions in Syria and Iraq used them to some extent, but they've really come into their own in Ukraine. /6
But how do you destroy an armoured vehicle with an off-the-shelf drone? Ukraine appears to have been using a few different approaches. One of the most effective has been to repurpose the RKG-3, an old Soviet-era type of anti-tank grenade dating to 1950. /7 Image
In 2020, Ukraine's PJSC Mayak Plant demonstrated a drone bomb conversion for the RKG-3 - attaching 3D-printed fins to convert it into the RKG-1600. It weighs about 1kg (2 lb), requiring the use of a larger drone. /8 Image
During testing, drone pilots were able to hit a target 1m (3ft) in size from an altitude of 300m (900 ft). At that altitude the drone would have been virtually invisible and inaudible. /9 Image
Another tactic appears to be the use of what are likely to be aerially-dropped mortar rounds - a very simple and cheap option, particularly against weakly armoured vehicles such as these Russian BMP-3s (with only about 10mm of top armour). /10 ImageImage
The effect of these can be seen in the video below. /11
The cost-effectiveness of these things is extraordinary. An octocopter drone costs maybe $10k, a Phantom 3 costs around $500. A mortar or RKG-1600 probably costs under $100. Each BMP-3 cost the Russians $796k. Add to that the potential cost of a lost crew. /12
You can bet that military strategists will be watching this with great interest. Drones are now able to effectively snipe soldiers and equipment with great precision, likely undetected, at any time of the day or night and in most weather conditions. /13
Even if you're camouflaged, bivouacked or behind the front lines, a drone armed with a small bomb could be overhead at any moment. Drone pilots are the new snipers of the 21st century, and are likely to be just as much feared by their targets. /end
An extra point about how effective those converted anti-tank grenades (RKG-1600) are: the most recent models of the base RKG-3 grenade can penetrate 220 mm of rolled homogeneous armour. That's more than enough to take out a tank, as this video shows:

1/ A real estate agent in Russia has aroused controversy for proposing a get-rich scheme: marry a Russian soldier and wait for him to get killed in order to claim his death benefits. Outraged Russian warbloggers say that such schemes are real and need to be stopped. ⬇️
2/ Marina Orlova, founder of the Tomsk agency "Real Estate Empire", has shared a "working plan" for Russian women over 30 to buy an apartment. "It's all easy and simple," she says, "You find a man who serves in the Special Military Operation. He dies, you get 8 million."
3/ Orlova says that "many people" use this scheme now. Not surprisingly, it has prompted outrage and has resulted in calls for her to be investigated. She says her statement was made as a "joke between girlfriends" in an interview and has apologised.

1/ A new poll shows a sharp rise in the number of Republicans who consider Canada, Ukraine and the EU to be enemies of the United States, and a drop in both Republicans and Democrats who consider Russia to be hostile. It shows the impact of Donald Trump's rhetoric. ⬇️ Image
2/ The Economist has published a YouGov poll showing how Trumpian rhetoric and agitation by pro-Trump outlets such as Fox News has transformed Republicans' views towards America's former allies, which have now been recast as enemies.
3/ Before the 2024 election, 12% of Republicans saw Canada as an enemy, and 17% saw the EU similarly. Those figures are now 27% and 29%, having doubled since Trump's return to the presidency.

1/ Russia aims to make up its huge war losses and declining population by encouraging schoolchildren to marry at 18, as part of a "special demographic operation." Some regions have introduced bonus payments for pregnant schoolgirls. ⬇️ Image
2/ Russian schools are to introduce a new course called "Family Studies", to be mandated for students at grades 5-9. The textbooks have already been developed. One section encourages schoolchildren to marry at the age of 18 and highlights the state's support for young families. Image
Image
3/ This includes benefits for families with children, maternity payments, mortgages for young families, and state support for large families. Parents with seven or more children are eligible for an 'Order of Parental Glory' medal, established by Putin in 2008. Image

1/ Ukraine's recent incursion into the Belgorod region east of Sumy has led to a windfall for Russian traffic police. Calling them "werewolves in uniform", Russian warbloggers accuse them of systematically robbing Russian troops responding to the Ukrainian offensive. ⬇️ Image
2/ Russia's police – military and civilian – are notoriously corrupt and, particularly in the case of the military police, have an odious reputation for robbing and even kidnapping military drivers in order to extort money from them.
3/ Now it seems that the Belgorod traffic police are getting in on the act. Russian warbloggers are responding with sarcasm and complaints:

1/ The Trump Administration's bid to force foreign companies around the world to obey its executive order banning diversity, equality and inclusivity (DEI) programmes may pose a stark choice: follow the laws in their own countries or stop doing business with the US government. ⬇️ Image
2/ As previously reported, US officials are sending letters to companies and institutions in multiple countries demanding that they discontinue internal DEI policies as a condition for being an approved supplier of goods or services to the US government.
3/ A US State Department official says: "U.S. embassies and consulates around the world, have communicated to grant-recipient entities, as well as suppliers of products and services, the new framework based on the recent executive orders signed by President Donald Trump."

1/ Ten likely doomed Russian soldiers have issued a desperate appeal from a cellar, where they say they have been sent into a "hopeless situation" without transport, ammunition, communications or even a map. They ask the Russian authorities to intervene against the commanders. ⬇️
2/ The men are from the 110th Motorised Rifle Brigade (military unit 42600), formerly a unit of the 'Donetsk People's Republic' People's Militia before its incorporation into the Russian army. The unit has an unenviable reputation for corruption and brutal treatment of its men.
3/ In the video, the men say they have "defended the land of Donbass, protected civilians for a long time, and now we have been sent to our death." They appear to be ex-convicts (along with one contract soldier) and are part of a 'Storm' assault brigade.
