@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/ Iran is seeking to establish a pay-to-sail regime in the Strait of Hormuz, under which it could earn over a quarter of a billion dollars a day. A senior member of the Iranian parliament says that vessels seeking to transit the strait will be charged $2 million each time. ⬇️
2/ The Financial Times and Rudaw report that the Iranian government intends to fully monetise the strait by forcing passing ships to pay a fee for each passage. The "new regime" has been announced on state television by Alaeddin Boroujerdi, a senior Iranian parliamentarian.
3/ Boroujerdi, a member of the parliament's National Security Committee, said that "For some ships which cross, for whatever reasons, Iran is charging them $2 million for the crossing ... In practice we have established a new regime governing the Strait of Hormuz after 47 years."
1/ Claims by pro-Russians that Ukrainian drone attacks on Russian Baltic ports went via Poland and the Baltic states have been met with scepticism by warblogger 'Fighterbomber'. If that's so, why has Russia not protested to those states?, he asks. ⬇️
2/ 'Fighterbomber', who has close links with the Russian Air Force, points out what Conan Doyle might have called the dog that didn't bark: the fact that the Russian government has said nothing about Ukrainian drones supposedly being routed over NATO territory:
3/ "Well, first of all, the airspace bordering Russia has been closed in countries like Poland and the Baltics for a long time.
Accusations from beauty bloggers that drones are being launched from the territory of these countries have been circulating for several years as well.
1/ With American ground forces building up in the Gulf region, much attention has been paid to Kharg Island in the northern Persian Gulf. But what about the Iranian-held islands in the Strait of Hormuz? Here's why they might be a higher priority for possible landings. ⬇️
2/ Seven Iranian-controlled islands punctuate the narrow strait between Iran and Oman: from west to east, Abu Musa, Greater and Lesser Tunb, Qeshm, Hengam, Larak and Hormuz itself. All are part of Iran's Hormozgan province.
3/ Two more Iranian islands, Bani Forur and Sirri, are located further west, in the Persian Gulf proper. They have strategic value as locations for reconnaissance, surveillance of shipping traffic, and possible interdiction. Both have an Iranian military presence.
1/ The Ukraine war is a "dead end" which "could last for a hundred years", according to a gloomy Russian commentary. The transparency of the battlefield and its domination by drones has made large offensives "downright impossible" and is causing vast numbers of casualties. ⬇️
2/ 'Voenkor Kotenok' has written a long and detailed analysis of the situation at the front lines, following similarly gloomy outlooks by other warbloggers (see the thread below).
3/ "I have repeatedly pointed out that the front in the Ukrainian theatre of military operations is in a stalemate. This situation took shape last year, marked by the Battle of Pokrovsk.
1/ An experiment by Russia's FSB has indicated that thousands of Russians are likely to be willing to carry out sabotage attacks on behalf of Ukraine or other foreign actors. In only three hours, the FSB recruited ten would-be saboteurs via Telegram. ⬇️
2/ Russia has experienced regular sabotage attacks carried out by people who have been recruited by foreign agents over the Internet, usually via Telegram. They are sometimes tricked into thinking they are working for the Russian security forces.
3/ More often, however, saboteurs act purely for money. Russia has used the same methodology to recruit saboteurs in Ukraine and elsewhere in Europe.
1/ Russian warbloggers are increasingly concluding that the war in Ukraine is stalemated and cannot be won by military means. Two prominent warbloggers have published gloomy commentaries explaining why. ⬇️
2/ 'Fighterbomber', a blogger with links to the Russian Air Force, comments:
"We still have 15% of Donbas left to liberate, and then Donbas will be liberated.
In my opinion, we have three main options."
3/ "The first is to continue the creeping offensive with varying success, regardless of losses, which will be, to put it mildly, very heavy.
Judging by the current slow pace, that [needs] at least five years.
