@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/ Ukraine's massive penetration of Moscow's air defences is sparking a great deal of gloomy and angry commentary from Russian warbloggers. The military-technical Telegram channel 'Atomic Cherry' warns of an escalating trend of Ukrainian capabilities. ⬇️
2/ "As an interim observation, I will note that the Armed Forces of Ukraine, for the first time in years of the conflict, have succeeded in destroying a number of targets in the Moscow region:
There are a number of statements and testimonies about hits on other targets as well, but listing them all makes no sense. The trend is clear without this.
1/ The Russian government is warning that the Ukrainians are trying to buy Russian Telegram channels that are now unprofitable after the government's blocking of the app. Russian commentators say it's an inevitable result of the government's restrictive policies. ⬇️
2/ Russia has been severely restricting Telegram since the start of April, as well as making it retrospectively illegal to use Telegram for advertising. This has been a disaster for Russian businesses, for which Telegram was an essential marketing tool.
3/ Individual Telegram bloggers have also faced a collapse in their income from Telegram, both because of the advertising ban and due to the blocking reducing their user bases (though many Russians continue to access it through VPNs). Some are now trying to sell their channels.
1/ Russia's anti-drone defences are said to be severely hampered by bureaucracy, such as bans on interceptor drones with explosive warheads, and legal liability, which makes mobile fire teams liable for damage caused by shot-down enemy drones. ⬇️
2/ Russian drone developer Alexey Chadayev looks for answers to the eternal question of "where air defence?". He highlights legal and bureaucratic obstacles that he says are major obstacles to the effective protection of facilities that are being targeted by Ukrainian drones:
3/ "A few thoughts on counter-drone defence of rear-area facilities.
1. The very fact that we have legally limited the ability to use explosives to combat drones in the rear leads to an increase, not a decrease, in collateral losses.
1/ The Poseidon intercontinental nuclear torpedo is a very stupid idea, says Russian writer and blogger Maxim Kalashnikov. He lambasts it as a huge waste of Russia's resources which is likely to be highly vulnerable to interception and wholly ineffective in practice. ⬇️
2/ Recent reports that the much-hyped Poseidon will soon be undergoing sea trials on a purpose-built carrier submarine have attracted a scathing response from Kalashnikov. He bluntly dismisses it as a very expensive and militarily pointless propaganda exercise:
3/ "I look upon the cult of the “Poseidon” torpedo with disdain. Is it aimed at complete idiots whose minds have been shaped by Hollywood and who’ve forgotten their high school physics? Or at impressionable retirees?
1/ Russia's shrunken Victory Day parade in Moscow on 9th May has been a TV ratings flop, reflecting a lack of public interest and its exceptionally short duration. Russian broadcasters report 25% fewer people tuning in this year. ⬇️
2/ The Russian news outlet 'We can explain' reports that the combined rating for the Victory Day Parade broadcast across the three main broadcasters (Channel One, Rossiya 1, and NTV) this year was only 16%. This is a near-25% drop from the 20.5% rating recorded in 2025.
3/ The parade was overtaken in the ratings by the wreath-laying ceremony at the Tomb of the Unknown Soldier. 'We can explain' suggests that this "may be due to the show's shortening and watering down."
1/ Russian warbloggers are mystified and angry at a recruitment advert for the Russian army posted on the Facebook-like social network VK. Unlike the usual ads, which show Russian soldiers as muscular supermen, it's attracting attention for being a lot more realistic. ⬇️
2/ Sergei Moskalkov, who spotted the advert, declares angrily:
"This isn't a fake, not a disinformation-like collage, but a genuine advertisement for contract service in the Russian Armed Forces.
This is a VK ad.
#fifthcolumn
#lawlessness"
3/ Lev Vershinin suggests a return to the classics:
"Since Sergei Moskalkov never lies and isn't particularly prone to jokes, I'll take it on faith."
