@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/ Igor 'Strelkov' Girkin predicts that Russia will be stripped to the bone – "IN THE EVENT OF DEFEAT, THEY WILL TAKE EVERYTHING FROM US—UP TO AND INCLUDING NUCLEAR WEAPONS AND SOVEREIGNTY" – in a long and deeply gloomy commentary posted on Telegram. ⬇️
2/ Girkin, who is currently in a prison for former security officials in the Kirov region, analyses the deteriorating situation in the war and warns that Russia is not going to end up in a good place:
3/ "Having taken a breather during the so-called "ceasefire," the enemy has begun a long-planned campaign to "isolate the front from the rear to great depth ," as many observers and authors have quite correctly noted.
1/ Russia's corrupt elites are drinking 'Long Epstein Island' cocktails in St Petersburg while soldiers and civilians die, Crimea is effectively cut off, the Donbas is under constant attack, and Russian defenders struggle, an angry Russian warblogger complains. ⬇️
2/ Anger and contempt at the excesses of the St Petersburg International Economic Forum (SPIEF) has become a widespread theme among Russian warbloggers, who almost all regard it as an expensive distraction from an increasingly difficult war.
3/ 'Ural PartiZan' writes:
"The elites [at the SPIEF] increasingly look like bourgeois citizens feasting on champagne-drenched pineapples and cold-smoked hazel grouse in 1917.
1/ Whatever Russian officials thinks they're achieving by hosting far-right influencer @RealCandaceO in St Petersburg, it's lost on Russia's warbloggers, who say they're dying of cringe. "They probably even licked the ass of that Yankee scum," one says appreciatively. ⬇️
2/ 'Belarusian Silovik' observes sarcastically:
"American journalist Candace Owens, who attended the SPIEF, posted a photo on X with Russian journalists who surrounded her.
Of course, she's a REAL AMERICAN."
3/ 'Pozdnyakov 3.0' wonders what on earth the Russian media is thinking: "American journalist Candace Owens posted a photo on her Twitter account where all the Russian media outlets vied with each other because she's an American, OH MY GOD, FROM AMERICA ITSELF. 😱😱😱😱😱"
1/ Vladimir Putin's unconvincing claim that Russia deliberately targeted a 'barn' in Ukraine to test the $50 million Oreshnik missile has produced scorn and incredulity among Russian warbloggers. "Fucking hell," says one flabbergasted warblogger. ⬇️
2/ On 24 May, Russia fired two Oreshnik IRBMs at Ukraine, with inert warheads. One demolised a garage complex at Bila Tservka near Kyiv; the other, embarassingly, fell short and landed in Russian-held territory.
3/ Speaking yesterday, Putin claimed that the garages (which he called "barns" for some reason) had been deliberately targeted to test the missile's accuracy. Russian warbloggers are not convinced, to put it mildly.
"Fucking hell", comments 'The Voivode Broadcasts'.
1/ A "time bomb" has detonated under Russian rumps. Botched attempts in the early 1990s to replicate Brazilian butt lifts are now disintegrating inside Russian backsides, causing buttocks to 'literally melt'. ⬇️
2/ 'Baza' reports:
"Thirty years later, the first post-Soviet buttock augmentations have become a shapeless mess and caused a ton of discomfort to their "owners."
3/ "Although thinness was popular among Russian women at the time, some dreamed of a "Brazilian butt" and opted for injections to achieve it. The procedure took only 20 minutes, and doctors didn't particularly bother with recovery.
1/ Ukraine appears to have attacked Russian aircraft under cover in concrete shelters, likely with drones flown into the entrances. Details are as yet scant. ⬇️
2/ "The 'Helicopterpilot' Telegram channel, written by a Russian military helicopter pilot, predicted on 27 May that "judging by how the Ukrainians are progressing and methodically whacking our air defence systems, oil refineries, trucks, and military equipment along the…
3/ …"land corridor to Crimea," if they're given the go-ahead and a ration of missiles, the next targets will be the hardened aircraft shelters.
Personally, I see this trend.
And it's more like a "when" than an "if."
So I don't know where their "catastrophic situation" is.
