@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/ Today's Ukrainian strikes against a Russian oil refinery in distant Omsk are being greeted with gloom by Russian warbloggers. They say that their predictions of increasingly wide-ranging Ukrainian raids were ignored, but are now coming true. ⬇️
"What happened is what was predicted last year: Ukrainian formations were able to reach Omsk, which is more than 2,500 km from the front line, with modernised FP-1 drones.
3/ "We believe that against this backdrop, discussions and debates about the involvement of Kazakhstani territory and various saboteurs will start again, but this is just a search for excuses, not a solution.
1/ Ukrainian drone manufacturer Fire Point's announcement that it has extended its FP-1 drone's range to 3,400 km (2,100 miles) is prompting alarm among Russian warbloggers. One notes that this puts many strategically vital sites in Siberia in range. ⬇️
"The head of Fire Point company, Denis Stiler, claims that the upgraded FP-1 drones can fly 3,400 km. Of course, he's just hype and lying! But if it's true, the following targets will be hit:
3/ "Tyumen Refinery (2,100 km) - already attacked in June, the fuel base of the country's main oil-producing region: gasoline and diesel are primarily used for domestic consumption in Western Siberia, including oil production itself.
1/ Frontline Russian soldiers are literally starving due to constant Ukrainian drone and artillery strikes preventing food deliveries, according to Russian accounts. In some cases, soldiers are said to be deliberately starving themselves so that they can be evacuated. ⬇️
2/ 'Northern Channel Plus' reports:
"The food situation in the 9th Motorised Rifle Regiment is quite dire. At the positions, or more accurately, in the holes, there is a severe shortage of food. Food deliveries are made every few days, and sometimes it can take a whole week."
3/ "It sounds scary, but the guys are truly starving. Sometimes, after a long period of hunger, their stomachs stop working when provisions are finally dropped or delivered to the front lines."
1/ Russian horse breeders are reporting booming sales due to the ongoing fuel crisis. Despite the expenses of owning a horse, they are now cheaper to maintain than constantly refuelling an SUV. ⬇️
"About a thousand horses were saved from slaughterhouses in Russia due to the rise in gasoline prices."
3/ "Villagers are increasingly buying four-legged animals instead of off-road vehicles - it's cheaper to get around off-road, go to the forest, mow hay, and engage in farming.
1/ Nikolai Patrushev, a key adviser to Vladimir Putin, says that Russia is fighting a pan-European neo-Nazi alliance, and advocates Russian naval action in the English Channel. He warns the Baltic states of "the end of ... peaceful, carefree life and sovereignty." ⬇️
2/ Patrushev is a former Secretary of Russia’s Security Council, a former head of the FSB, and a highly influential presidential adviser. He has been spoken of as a possible successor to Putin. Like Putin, he has often shown an extremely paranoid, aggressive worldview.
3/ This outlook is on display in an interview headlined "When War Is on the Doorstep" with Russia's main state newspaper, Rossiyskaya Gazeta, in which he addresses his views on the war in Ukraine and Russia's wider geopolitical situation.
1/ Russia's former chief doctor Gennady Onishchenko says that the current fuel crisis is positively beneficial for Russia: it's making the air cleaner, and city residents are becoming fitter by being deprived of their cars. Russian commentators are wondering what he's smoking. ⬇️
2/ The comments were made by Onishchenko, an academician of the Russian Academy of Sciences, in an interview on Friday with the Moscow Speaks radio station:
3/ "We even stopped walking to the neighbouring [building] entrance and started driving in cars. If we talk about Moscow, it's much more sensible to give up cars. Most people can easily and comfortably ride the metro, and leave cars for trips outside the city.
