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 Russian soldier has recorded a video in advance of his own anticipated murder, speaking about how his commander has executed and buried other members of his unit, as well as hoarding aid meant for the soldiers. The speaker has since disappeared and is now likely dead too. ⬇️
2/ Pre-murder videos are a distinct genre of selfie videos made by Russian soldiers (see below for a couple more examples). They explain calmly why they are about to be killed – generally because they have complained about corrupt officers or disobeyed orders.

3/ Two Russian warbloggers highlight what has been going on there. 'Callsign OSETIN' writes:

"Fighting continues on the islands in the Kherson direction (slightly less frequently, but it's still happening). Few people write about it, but our men on the islands are true heroes. Image
