@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 Deputy Commander-in-Chief of the Russian Navy, Mikhail Gudkov, may have inadvertently revealed his position in an insecure radio call, enabling Ukraine to kill him on Wednesday. Ukraine may also have tried to assassinated him on 30 May near Vladivostok. ⬇️
2/ Gudkov was reported to have been killed on 2 July at Korenevo in the Kursk region by a Ukrainian missile strike. The VChK-OGPU Telegram channel reports that the general may have inadvertently given away his own position to Ukrainian signals interception.
3/ The channel reports that according to an account that is circulating, on 2 May "Vladivostok celebrated its City Day. The military, including Mikhail Gudkov, while in the Kursk region, could call each other and exchange congratulations over an unprotected connection."
1/ Russian prisoners of war are being sent straight into to front line assault squads after being released from Ukrainian captivity. They are denied family reunions, interrogated by the FSB, and in some cases prosecuted. Many have attempted suicide. ⬇️
2/ Relatives of released Russian POWs have appealed to the Russian authorities to allow their loved ones to return home. Instead, they say, the men are being sent straight back into combat without even being able to see their families.
3/ In one video appeal published last month, the wife of captured Russian soldier Alexey Frolov says that he is awaiting his turn to be exchanged after a year in captivity. She asks the authorities to let him come home, rather than being sent straight back.
1/ Russian Railways is facing a worsening crisis. 300,000 disused railway wagons are congesting the network, entire freight trains have been abandoned for months, there are critical shortages of locomotives and workers, and a major drop in loading across the network. ⬇️
2/ Russian Railways (RZD) has been in trouble for several years. It is facing an extremely severe shortage of staff, with some divisions of the company reportedly as much as 60% understaffed.
3/ RZD's problems have a huge impact on Russia's economy. It handles 47% of all cargo transport in Russia, and as much as 87% if pipelines are excluded. It's vital to the economy and the Russian military alike, as Russia's roads can't accomodate all the freight carried by rail.
1/ Economic distress in Russia is being reflected in a sharp increase from 1 July 2025 in tariffs for housing and municipal services – by up to 40% in some regions. This comes on top of steadily higher tariffs in 2023 and 2024, with an accelerating yearly level of price rises. ⬇️
2/ ASTRA reports that tariffs in the regions will increase by between 8.6% in Amur to 21.1% in Perm. Moscow's tariffs will rise by 15%, the surrounding Moscow Region by 13.3% and St. Petersburg by 14.6%.
3/ Some local authorities can impose their own increases independently of the framework established by the central government. Thus Omsk is increasing its tariffs by 39.6%, and Izhevsk by 38%.
1/ Russians who have lost arms, legs or eyes are being sent into assaults in Ukraine, with little chance of survival. Despite severe injuries, they are either being denied a fitness assessment or are arbitrarily being rated fit. The men call themselves "meat on crutches". ⬇️
2/ A Russian soldier has spoken of his experiences with a so-called 'cripple battalion' – a unit comprised of injured soldiers, which rather than recuperating or being allowed to heal or get treatment, is sent to the front line to take part in fresh assaults.
3/ 37-year-old Anton Savchenko from Tyumen – an ethnic Ukrainian with many relatives in Ukraine – volunteered to go to war in October 2024, saying that he "had to help". However, he soon regretted it, according to his relatives. Within less than a month, he had lost his left eye.
1/ Tens of gigabytes of secret data on Russia's strategic electronic warfare systems has been hacked by the pro-Ukrainian Russian Volunteer Corps (RDK). They say that Russia's EW shield is "not just fragile - it's full of holes" due to multiple flaws and vulnerabilities. ⬇️
2/ Two weeks ago, the RDK announced that it had obtained a large quantity of data on Russia's EW systems, including technical specifications, diagrams, official correspondence, equipment setup methods, drawings, test reports, and functional information.
3/ RDK commander 'Fortuna' says that "We got more than just the external appearance. We see the internal logic, architecture, connections between nodes, we know who designed it, which companies supplied the units, which research institutes are responsible for the developments."
