@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
2/ This photo shows the Project 06363 (Kilo class) submarine Mozhaisk and Project 877EKM (Kilo class, built for tropical waters) submarine Dmitrov, equipped with anti-drone protection, in Kronstadt near St. Petersburg.
3/ The first submarine's defensive armament consists of a heavy machine gun, likely intended for use against unmanned surface vessels (USVs), which is mounted on a turret aft of the keel, and a searchlight on the navigation bridge.
1/ A high-profile figure in Russian drone development has been arrested on charges of large-scale fraud. It's another illustration of how Russia's pervasive corruption is hampering its efforts to become a leading developer and producer of drone technology. ⬇️
2/ On Friday 8 May, the Sverdlovsky District Court of Belgorod arrested Yuri Kozarenko, former CEO of Transport of the Future LLC, and sent him to a pre-trial detention centre. He is under investigation for alleged large-scale fraud; details have not yet been released.
3/ Kozarenko, 36, is a native of the Belgorod region and did his military service in the Russian Naval Infantry (Marines). He joined the EFKO Group of Companies in 2012 and rose to become the head of the corporate university and innovation centre.
1/ A new military treaty between Russia and Nicaragua has gone into force, enabling Russia to base troops, special forces, and surveillance facilities in the Central American country. However, warns a warblogger, it's now potentially Russia's last strongpoint in the Americas. ⬇️
2/ Russia and Nicaragua have maintained close defence ties for decades, dating back to Soviet-era support for the Sandinista government in the 1980s. Cooperation has deepened under President Daniel Ortega, with a new agreement signed in November 2025 and now ratified by Russia.
3/ Nicaragua relies heavily on Russian (and former Soviet) military equipment—reportedly about 90% of its arms imports—and has received recent donations such as helicopters, transport aircraft, air defence systems, and tanks.
1/ With Donald Trump ("our Trumpushka") increasingly seen as irrelevant to the war in Ukraine, Russian warbloggers are increasingly calling for "demonstrative strikes" on the EU, UK and Canada to force them to cease support for Ukraine and negotiate a peace settlement. ⬇️
2/ On 15 April 2026, Russia’s Ministry of Defence published detailed lists of European companies and facilities it claimed were producing strike drones (UAVs) and components for Ukraine. It explicitly framed these joint production sites as "potential targets".
3/ This has led to calls from Russian warbloggers to attack the facilities. Alexey Zhivov posted a particularly lurid example of this a couple of weeks ago (see thread below). 'Pint of Reason' provides a strategic rationale for Russia to do so.
1/ If yesterday's Victory Day parade had been a true reflection of Russia's frontline army as it is now, it would have been a chaotic display of battered vehicles, motorbikes, exhausted soldiers on crutches, and donkeys. A Russian warblogger imagines how it could have been. ⬇️
2/ 'Jon Snow and the Second Singer' writes:
"A parade. It will be led by children carrying portraits of their fathers—old photographs, of course, from their civilian lives, from that time.
Mavic 3 drones will fly overhead.
3/ "Next will come a thin line of Chinese enduro bikes, dirty to the point of being colorless, with riders dressed in whatever’s available at Chechen military surplus stores: pink Chinese cartoon T-shirts, 5-ruble hats, 5.11 caps, and backpacks from Avito.
1/ Ahead of Russia's Victory Day celebrations tomorrow, Russian nationalists are engaged in their traditional pastime of rewriting history to erase the Hitler-Stalin alliance. It was all the fault of the "main bastards", the perfidious British, according to one warblogger. ⬇️
2/ 'Historian' Maxim Ravreba asks on his eponymous Telegram channel, "Who started World War II?", and turns to that well-known impartial source, Adolf Hitler, for the answer:
3/ "A few days before the German-Polish war, I proposed a solution to the British ambassador in Berlin—one under international control. It was rejected because influential British politicians wanted war."
