@solonko1648, who's a serving Ukrainian soldier, has published an excellent pair of threads in Ukrainian describing how the Russian system of trenches and firing positions works. It's a very helpful insight into why they have been so difficult to overcome.
He focuses on a Russian fortified stronghold between the villages of Robotyne and Novoprokopivka, through which the road from one village to the other runs. Tokmak lies further along the same road, which is currently contested. The following thread translates his description:
By @solonko1648:
This, dear friends, is one of the most difficult strongholds located in the Robotyne-Novoprokopivka area. A complex system of trenches-tunnels, dugouts, firing positions, to which the Russian invaders cling with all their might... 🧵 /1
What we see first. A system of trenches and firing positions. From observation and tracking of the movements of the occupiers' equipment and personnel, we confirm movement and approach routes to the position. /2
In general, these routes should be obvious, but of course, all the data should be studied and the information verified. That's why this is a formal process. Next, we see from above how these positions are equipped. We see the overlapping of dugouts. /3
But that's not all. Some of the trenches are covered over for a long distance. They may not be tunnels in the classical sense, but technically they are. This is actually a trench-tunnel, designed to hide the number of personnel and their movements in the trenches. /4
With the help of aerial reconnaissance, we determine not only which route the occupiers take to enter/leave. We also identify the entrances/exits of this stronghold/trench system. /5
A little more about the "tunnels". According to the soldiers of the frontline units, there is a classic tunnel here. It's under the road that leads from Robotyne to Novoprokopivka. It connects both flanks of this system. /6
Moreover, we also know that dugouts have been dug here, which actually have a second underground floor, going deep into the ground. While we were waiting for the shells, the occupiers were digging. And they dug long and deep. /7
After fierce fighting and artillery shelling, our artillery "opened" the dugouts and covered trenches. After that, it became clearer how much more difficult the task was. 8/
Furthermore, in the area where the main entrance to these positions is located from the west, it is only after a dense artillery barrage that the untrained eye will become aware of how well some of the trench-tunnels on this side were camouflaged. /9
The occupiers successfully used the forest belt to prepare and camouflage these positions. Such positions require us to conduct very thorough and vigilant reconnaissance. The occupiers know what we are interested in and try prevent us from conducting it properly. /10
You can watch the process in this video. /11
Now I will talk about the eastern part of the fortification. /12
It is not so much a separate fortified point as part of an extensive system, overcoming which was an extremely difficult task, taking into account the features of the hostilities, the terrain and the ratio of forces and means that I talked about. /13
The two main parts of the fortifications are connected by an underground tunnel that runs under the road. This way, the road is controlled and still used for its intended purpose. /14
Note the shape of the trench in front of the forest plantation (except for the area near the road). We have already seen a similar structure on the defence line that stretched northwest of Verbove. /15
Also note another example of the use of terrain. The system of fortifications uses the plantation to cover the entrance and exit. There are also fortifications in the rear. A circular defence pattern is observed. /16
Here, too, the artillery of the Ukrainian Armed Forces performed the task of "opening" the trenches built in the style of tunnels. A similar picture could be seen in the western part of these fortifications on the other side of the road, which I analysed earlier. /17
Also note the layout of the trenches closer to the road. Imagine what it would be like to storm/clear them. Another sceptical remark to the adherents of "elastic defence". No one was going to leave here even to return. They clung to this stronghold with all their might. /18
And then there's the wormhole. Another reminder that some people like to call the Russian invaders worms. /19
1/ A "time bomb" has detonated under Russian rumps. Botched attempts in the early 1990s to replicate Brazilian butt lifts are now disintegrating inside Russian backsides, causing buttocks to 'literally melt'. ⬇️
2/ 'Baza' reports:
"Thirty years later, the first post-Soviet buttock augmentations have become a shapeless mess and caused a ton of discomfort to their "owners."
3/ "Although thinness was popular among Russian women at the time, some dreamed of a "Brazilian butt" and opted for injections to achieve it. The procedure took only 20 minutes, and doctors didn't particularly bother with recovery.
1/ A Russian soldier serving in Ukraine says that the situation is terrible and getting worse. "It’s absolute chaos over here with all the bodies right now ... the action is getting heavier and heavier every day. We're just a bunch of fucking losers." ⬇️
2/ Russian warbloggers are becoming increasingly outspoken in describing how the war is going badly for their side. 'When the cannons start singing' publishes an account from a reader who is with the Russian Army in Ukraine:
3/ "It’s absolute chaos over here with all the bodies right now, and even without the bodies, I could sneakily film the road we're bringing people in on, it's a complete mess.
1/ Russian warbloggers are reacting with shock and alarm at the Ukrainian attack today on the Russian Baltic Fleet corvette Boykiy near St Petersburg. In particular, they question the apparent lack of effective air defences or anti-drone protection. ⬇️
2/ 'Rybar' comments: "The threat to the fleet is everywhere."
"Judging by the video, at least two hits were recorded. The corvette was in dry dock undergoing repairs, despite the ship being new. And Ukrainian forces intercepted it there."
3/ "They had already done something similar during attacks on Sevastopol several years earlier.
The hit on the Boykiy once again exposes the problem of countering UAVs.
1/ Accused rapist and sex trafficker Andrew Tate is visiting Russia. The news has disturbed Russian warbloggers, who suggest that Russia, which has recruited literal cannibals into its army, should aspire to a higher standard. ⬇️
Popular English-speaking blogger Andrew Tate has published a post with an unambiguous hint of a visit to Russia."
3/ "Timing-wise, this coincides with the St Petersburg International Economic Forum, where Western influencers have been actively invited in recent years — as a demonstration that ‘not everyone in the West is against Russia’.
1/ The Russian-occupied city of Donetsk in eastern Ukraine is under a 'drone siege', according to local inhabitants. Ukrainian drones are striking targets across the city and the surrounding region. A resident provides a vivid eyewitness account. ⬇️
2/ 'Donetsk MartynoVa', a pro-Russian resident of Donetsk who positions herself as an influencer and Telegram blogger, has been writing about the deteriorating situation over the past month. On 11 May, she wrote:
3/ "The news brings information that drones are already harassing the land corridor, but, judging by the number of cars from Crimea, this doesn't stop many [travellers]."
By 18 May, the drone campaign had been stepped up:
1/ Russia's captured and corrupted bureaucracy, which is under the thumb of powerful industrial concerns and complicit politicians, is strangling independent developers of military electronics. Several developers are complaining about the situation. ⬇️
2/ Gagaring Lab, a developer of drone detectors and other military electronics, highlights how the 'People's Military-Industrial Complex' is being throttled:
"China launched a new strategy in February. China wants to be not only the world's factory, but also its laboratory."
3/ "Programmes have been launched to attract R&D companies to China. In Russian: welcome, developers, we will create the conditions for you. And here, people are worried about developers running away, but not about entire companies running away.
