@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/ The paranoia of the Russian authorities is killing vital hypersonic missile research, say Russian warbloggers following the conviction of two researchers for publishing a paper on air intake design. As a result, they say, practically nobody now wants to work on hypersonics. ⬇️
2/ Two physicists have been convicted of treason and sentenced to 12½ years in a maximum-security penal colony. The two men – senior researcher Valery Zvegintsev and associate professor Vladislav Galkin – are the latest in a series of scientists to be jailed in the last 2 years.
3/ Given their ages and poor health – Zvegintsev is 82 and Galkin is 71 – supporters say that their prison terms are effectively death sentences.
1/ The appointment of Colonel General Alexander Chaiko as the new head of Russia's Aerospace Forces is being criticised by Russian warbloggers, who point to his failure to take Kyiv in February-March 2022. It's being called a reward for incompetence. ⬇️
2/ 'Imperium Z' is harshly critical of Chaiko's record, with an only slightly veiled criticism of Putin as well:
"As we've written repeatedly, personnel issues are the main problem facing the current government in general and the president in particular."
3/ "Every appointment represents another descent down the ladder of qualifications and competencies, into the basement of nepotism, loyalty, and the convenience of superiors.
1/ It's not just this Saturday's Victory Day parade that's been cancelled or cut back in Moscow; so too has the city's annual cleanup, for the first time in over a hundred years. The city will have to remain dirty for another year. ⬇️
2/ Cleanup days, or subbotniks, originated in the spring of 1919 under Lenin's rule. They started as voluntary events mainly for communists (Komsomol members) and sympathisers. In later years, they became a familiar, characteristic feature of the "socialist way of life."
3/ Party ideologists viewed subbotniks as a means of "communist education of the masses". Participation in subbotniks became a measure of an individual's social activity, and the few who shied away could be subject to public censure or even administrative action.
1/ A senior Russian official has condemned Amazon's 'Fallout' TV series for rotting the brains of the Russian people. He calls for what amounts to an uplifting Russian version of 'Fallout' as a corrective. Russian commentators are scornful about what they call his "nonsense". ⬇️
2/ The Russian newspaper Vedemosti reports that Alexey Semenov, Deputy Head of the Presidential Directorate for Monitoring and Analysis of Social Processes, says Russia needs a "state order for a bright future".
3/ In an article, "The Architecture of the Future – Constructing Meanings," published in issue No. 5 of the journal "Gosudarstvo" ('State'), Semenov specifically calls out the US TV shows 'Fallout' and 'Paradise' for criticism.
1/ Since March 2026, Ukraine has been using AI-controlled Hornet kamikaze drones to attack Russian targets. They have excelled in action, causing carnage among the Russians. A crashed example permits a detailed look at how it works. ⬇️
2/ The Russian Telegram channel 'Hammer of the Witches', which focuses on UAVs, has taken a look at an example of a Hornet which crashed in a nearly intact condition. It calls the lightweight drone "the most dangerous threat to our rear logistics."
3/ The drone is made from foam and moulded plastic, with a wingspan of 2.2m and a length of 1.4m. It weighs about 5 kg without its payload and battery, and is propelled by a 300kv electric motor powered by a 10,000mAh battery. Its range is 60-70 km with a top speed of 120 km/h.
1/ As a peace deal is reportedly mooted in the Middle East, a new analysis by Barclays Research highlights the urgent need for a reopening of the Strait of Hormuz. It reports that the world is running out of runway, and increasing demand destruction will happen from late May. ⬇️
2/ Barclays describes the current situation – in which a huge drop in oil availability is being cushioned temporarily by an equally huge draw on stockpiles – as "living off the insurance". It uses the striking analogy of "a household that loses its income and lives off savings":
3/ "Month one feels fine. Month two is manageable. Month four is when you start skipping things. The world economy is somewhere around month two. The savings account is still positive.
