@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/ Russian forces have suffered a major defeat near Lyman, with the loss of numerous men and armoured vehicles. The survivors complain that the Ukrainians "fucked us up like pigs at the slaughterhouse" and accuse a Russian general of a reckless gamble. ⬇️
2/ A frontline soldier writing in the 'Management Speaks' Telegram channel gives a furious and graphic account of what happened, in a since-deleted post that also highlights the ongoing collapse in fundraising since Telegram was blocked for many Russians:
3/ "Brothers, no matter what kind of fuckery happens, I'm in it till the very end. I won't lie — they fucked us up like pigs at the slaughterhouse, and I'm ashamed of this shit in front of the families of the guys, not in front of you.
1/ Has Donald Trump accidentally recreated, in an even more severe form, the energy crisis that doomed Jimmy Carter's presidency? A comparison with the 1979 oil crisis shows worrying parallels with the current situation. ⬇️
2/ In August 2023, former Fed chair Larry Summers (@LHSummers) noted this in the Washington Post: "It is sobering to recall that the shape of the past decade’s inflation curve almost perfectly shadows its path from 1966 to 1976 before it accelerated in the late 1970s."
3/ What caused that acceleration? The most immediate trigger was the Iranian Revolution in early 1979, which brought Ayatollah Khomeini to power. The turmoil caused by the revolution caused Iran's oil exports to drop from about 6 million barrels per day to only about 1.5 million.
1/ As the Russian government's strangulation of the Internet deepens, Russian businesses are waking up to the long-feared reality of the so-called 'Cheburnet' – a walled-off national intranet for only selected companies and services. Economic disaster is forecast. ⬇️
2/ 'Cheburnet' (a portmenteau of 'Internet' and the iconic Soviet/Russian children's character Cheburashka) is the standard, sardonic Russian term for the government's long-held ambition to create a North Korea-style 'sovereign Internet', walled off from the outside world.
3/ Unlike North Korea or China, which never had uncensored access to the global Internet and have built their online economies and infrastructure accordingly, Russia is suddenly being wrenched onto the path of a closed national intranet.
1/ India is ripping off Russia to the tune of hundreds of billions of dollars over oil shipments, according to an angry Russian commentary. India will not pay for Russian oil in anything other than Indian rupees and Indian-made goods, which Russian companies don't want. ⬇️
2/ 'Political Report' writes:
"For several years, Russian officials proudly declared that Europe, by rejecting Russian oil, was only harming itself, while Russia continued to quietly sell its oil to other buyers and enrich itself."
3/ "It was claimed that India was happily buying up barrels at favourable prices. Public figures were aired about the colossal profits the country was supposedly receiving from redirecting supplies to the Asian market. The reality turned out to be far from these rosy reports.
1/ Russian sources say that Ukraine's Unmanned Systems Forces, under the command of Robert “Madyar” Brovdi, have made "significant strides in UAV production and deployment technology". Russian soldiers are facing "slaughter [like] cattle" as a result. ⬇️
2/ Andrey Medvedev writes:
"We've been reporting since the fall that the Ukrainian Armed Forces and Ukrainian drone manufacturers have made significant strides in UAV production and deployment technology.
3/ "Footage of a single Russian soldier being killed by ten to twenty drones has, unfortunately, been appearing regularly on the Ukrainian segment of Telegram.
1/ Another Russian helicopter has been lost over Ukraine – the second in two days, after yesterday's shootdown of a Ka-52 by an FPV drone (seen here). The Russian warblogger 'Fighterbomber' is angry at the lack of EW protection on helicopters. ⬇️
It's clear that everyone is now preoccupied with urgently installing anti-FPV drone electronic warfare systems on attack helicopters."
3/ "Why attack helicopters, specifically? Because Mi-8 crews are already carrying homemade electronic warfare systems at their own risk, supported by sponsors, volunteers, or even purchased at their own expense.
