@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/ Russia launched the full-scale invasion of Ukraine in February 2022 with the expectation that it would be a quick intervention lasting only a few weeks. Its soldiers went to war lacking a wide range of what turned out to be essential skills. ⬇️
2/ 'Vault No. 8', a serving Russian soldier warblogging on Telegram, recalls the lack of preparedness for an extended conflict among pre-war contract (professional) soldiers when the invasion was launched on 24 February 2022:
3/ "1. Level of training.
According to the regular personnel themselves, they were proficient with the weapons and equipment assigned to them—they could repair and operate them. At the level of training they had.
1/ Russia appears all but certain to fully block Telegram on 1 April 2026, on the grounds that it promotes frauds, disinformation, and violence. The Russian army has many similar problems; one Russian warblogger asks if the government should consider blocking the army instead. ⬇️

"In the light of Roskomnadzor's latest attack on Telegram, it's time to explore some new ideas.
Let me remind you of a recent TASS report (I quote):
"Telegram blocked over 235,000 channels in one day, but the problem is systemic.
3/ "Deputy Anton Nemkin expressed this opinion in a conversation with TASS:
'But let's call things by their proper names: if the number of blocked communities is in the millions, then the problem is not isolated, but systemic.'
1/ The AI boom is leading to drastically higher prices and possible shortages of the Chinese-made fibre-optic cables used by many Russian kamikaze drones. Prices have nearly quadrupled due to a massive increase in demand for fibre optics by data centres. ⬇️
2/ According to Russian media reports, Russian buyers are having to pay between 2.5 to 4 times more for fibre optic cable per kilometre than last year. By 2025, Russia was purchasing about 10.5% of all fibre optic cable produced globally – equivalent to 60 million kilometres.
3/ Russia is entirely dependent on Chinese fibre optic manufacturers. Its only domestic fibre optic manufacturer, JSC Optic Fiber Systems in Saransk, was destroyed by Ukrainian drone strikes in April-May 2025.
1/ Former Russian foreign ministry spokesman Mikhail Demurin is very gloomy about Russia's prospects after four years of full-scale war in Ukraine. He criticises the country's "feudal-capitalist regime of revenge" and asks whether Vladimir Putin will "lead it to its decline". ⬇️
2/ Writing on his Telegram channel, Demurin – whose views reflect an ultra-nationalist constituency that has been disappointed by Putin's perceived lacklustre approach to the war – is explicitly critical of Putin's leadership:
3/ "On the fourth anniversary of the launch of the Special Military Operation, I have nothing inspiring to say. The reshaping of Ukraine along Nazi and anti-Russian lines, its militarisation, and the NATO takeover of its territory and political space required a rebuff—that's…
1/ Russian warbloggers continue to reflect on the war in Ukraine entering its fifth year. The 'hurrah-patriotism' of 2022 is now long gone and the mood is bleak. Nikita Tretyakov says there is "nothing left to hope for; all hopes and illusions have been shattered". ⬇️
2/ In comments that illustrate the political dangers which the Putin regime will face when the war ends, Tretyakov – a mobilised paratrooper, military correspondent, and volunteer – writes on his Telegram channel:
3/ "Four years of war is a monstrously long and daunting time. As culture and history have taught us, such an anniversary demands some analysis, conclusions, and a summing up of interim results...
1/ Igor 'Strelkov' Girkin is marking the fourth anniversary of Russia's full-scale invasion of Ukraine – after eight years of war in Donbas, which he did much to start – but he isn't celebrating. He sees a "bleak" outlook of mutual exhaustion, caused by poor leadership. ⬇️
2/ Girkin writes from the prison where he is now half-way through a sentence for "inciting extremism" (i.e. criticising the Russian government's mismanagement of the war):
3/ "Today officially marks the fourth anniversary of the start of the Special Military Operation (although according to some sources, it began two days earlier, but was announced to begin on 24 February 2022).
We arrived at this significant date with extremely negative results.
