Defensive fortifications sighted all over #Ukraine 🇺🇦

Building defenses is nothing new in Ukraine, the first ones were built in 2014 along the Donbass frontline.
However, since a few months, a nationwide program has been set up to protect Ukraine.

🧵THREAD🧵1/24 ⬇️ Image
It is known that each oblast (or region) got allocated a budget to pay companies which will dig trenches and build bunkers.

Everything began in late january.

There are a few directions with priority: Zaporizhia, Odessa, Kherson, Donetsk or Kharkiv. Image
Before 2024, there were already defensive lines. For example, one was lying in front of Mykolaiv, one was south of Pokrovsk, one east of Kramatorsk...

These lines were mainly composed of some trench networks hundreds meters from each other. Image
In some part of the front, no defenses were built. This is exactly the case of Avdiivka. In fact, the city itself was defended with its old 2014/2015 bunkers.

However, the northern flank was not dug in, and the Russian managed to bypass the city and encircle it. Image
When Syrski was nominated, he ordered a nationwide program, even if Zalujny already begun before to build defenses.

3 months after, we can see a few interesting things. Image
First of all, and before I begin, I recommend you to follow the account of my Think Tank with other guys, @atummundi.

Begginning with Odessa.

This region is really important for Ukraine defenses since it is their only access to the sea.

They have to defend at least 3 directions :
-Black sea
-The corridor from Mykolaiv
-The border with Transnistria Image
For now, i have mapped some defenses east and north of the city but also on the seafront.

As you can see, there are some defenses positions west of the city itself, defending the border with Transnistria, a pro-Russian separatist state. Image
I think it is clearly impossible for Russia to reach Odessa. Why ? Because most of their landing ships are out of use and the Dnipro river is a good natural obstacle.
However, they are still building defenses : Image
Between Kherson and Mykolaiv, I mapped 3 lines.

The old one in front of the city of Mykolaiv, a new one, which is huge, going from the sea to Krivi Rih, and some trenches on the right bank of the river. Image
On Zaporizhia direction, multiple defenses are being built. Some are including bunkers and firing positions.

On the direction of Orikhiv, the Ukrainian are using old Russian defenses, + Zaporizhia line of defense and a new line stretching from Zaporijia to Donetsk. Image
This defensive line is huge, with anti-tank ditches, trenches, dragon teeths and sometimes bunkers. This was built between 20th February and today.
This line is mainly following the terrain, rivers and lakes. Part of it is present in Dnipropetrovsk oblast and finishing itself near the Mokri Yali river in southern Donetsk oblast. Image
Kourakhove is now a well defended city, while the approch to Pokrovsk, north of it, is defended by two main lines.
Fortification work is still underway in the region. Image
North of it, the defenses west of Avdiivka are being improved, while a line seems to be building east of Pokrovsk with the first scares of anti-tank ditches. Image
To see Kramatorsk defenses, you need to look east.

Make sure to click to see everything. Image
Here is Lyman being reinforced these days : the Russians are still trying to reach the Zherebets river near Terny but are failling for now. Image
Here is the city of Borova from Sentinel-2: you can see Ukrainian defenses on each red dot.
It is most of the time difficult to locate them and to be 100% sure it is one defensive position. Image
It is the first time I present a map of Ukrainian fortifications ongoing on the Russian border.

As you can see on the map, it is only the beggining, however, it will soon be improved to maintain a defense on Russian and Belarussian axis. Image
Here is an example south of Vovtchansk in Kharkiv oblast.
Soumy, Tchernihiv region, Kyiv city (fortifications from 2022) and Rivne oblast on the Belarussian border.

You have to understand this work takes hours to find, map and draw fortifications.

Just an example of my encouter on Tchernihiv direction, most of the time their are clouds, the luminosity is not always the same and it is a really tough job.
Here you will find high resolution images of these fortifications.

A Pokrovsk et Soumy, l'armée russe 🇷🇺 stoppée par les contre-attaques ukrainiennes 🇺🇦 change de stratégie.

Echouant à exploiter la percée de Dobropilla, l'armée russe pousse à Lyman et Pokrovsk'e, alors qu'elle est encore loin de ses objectifs de 2025.

🧵THREAD🧵1/25 ⬇️Image
Si 2023 fut une année à deux objectifs, mettre un terme aux perspectives offensives ukrainiennes et sécuriser le nord de Donetsk avec Bakhmout, 2024 fut l'année de la dernière bataille de Donetsk, permettant de repousser les ukrainiens loin de la ville, jusqu'à Pokrovsk. Image
Image
Pour 2025, même si nous ne pouvons pas le confirmer avec certitudes, le principal objectif russe était de préparer le terrain pour la "libération" finale de l'oblast de Donetsk, "prévue" pour 2026

Pour cela, il faut sécuriser Pokrovsk et Kostiantynivka, les deux principaux buts. Image

From Poland 🇵🇱 to Moldova 🇲🇩 stretches the longest Ukrainian 🇺🇦 defensive line, 2 800 km !

The biggest fortification system is in the east, in Donbass, but we can also find massive fortifications near Belarus, Kharkiv, or Odessa.

Let's analyse what is new :

🧵THREAD🧵1/25 ⬇️Image
Since 2014, ukrainian forces have been fortifying the frontline, primarly with trenches, dugouts and bunkers.

In 2022, 2023 and 2024, they also added new defensive lines everywhere, with anti-tank ditches and open-air trenches, which are now obsolete. 2025 saw a new program : Image
Previous trenches and fortifications were obsolete, no dugouts, no firing positions, no cover against drones and too large for small infantry teams.

Thus, since the first months of 2025, we have seen a new strategy of trench and fortification building. Image

For only 3 weeks, russian 🇷🇺 airforce launched 1 500 airstrikes between Pokrovsk and Kostiantynivka, more than the previous monthly count.

Up to 40% of all russian airstrikes are happening in Pokrovsk in preparation for a larger offensive which may soon happen.

🧵THREAD🧵1/20⬇️Image
I've never documented that much airstrikes in this area since I'm counting them. I started on june 11th, counting may and until june 11th.

From july 11th to august 11th, I mapped 1 400 airstrikes in 4 weeks, from august 11th to september 3, I mapped additional 1 500 airstrikes. Image
This graph from @M0nstas shows the large increase in the use of airstrikes "bombs".

From 1 000 a month in 2024 to an average of 3 000 to 5 000 a month, especially in april with more than 5 000.

This month of august, 4 400 ! I estimate ~1 800 are from Pokrovsk, 40% ! Image

En Hongrie 🇭🇺, le pion de Moscou 🇷🇺 dans la tourmente

En pleine crise diplomatique avec Kyiv 🇺🇦 et Varsovie 🇵🇱, Orban fait aussi face à une importante défiance interne, menée par Peter Magyar

La Hongrie, entre affaires de corruption, noyautage et répression

🧵THREAD🧵1/22 ⬇️Image
J'ai passé 6 mois en Erasmus 🇪🇺 en Hongrie. De manière générale, j'ai été frappé par ce côté très revanchard de la population hongroise envers le traité de Trianon il y a plus de 100 ans.

A part à Budapest, seule ville plus progressiste, et encore, la gauche n'existe presque pas Image
La droite et l'extrême droite forment environ 70% du paysage politique hongrois.

Le leader actuel est Viktor Orban, réélu premier ministre depuis 2010, son principal opposant est un ancien allié, Péter Magyar. Image

Russian 🇷🇺 airforce launched 700 NEW airstrikes near Pokrovsk 🇺🇦 in 2 weeks, with more than 80% in the Pokrovsk-Dobropilla direction.

To sustain its offensives operations, Moscow also launched 800 strikes at Lyman and Siversk and 2 800 at Sumy !

1- Pokrovsk-Kostiantynivka

Since may, I'm mapping most of russian airstrikes betwee, the two key cities of Pokrovsk and Kostiantynivka.

The frontline is 50km long and I mapped around 3 800 airstrikes there in 4 months ! Image
Here, you can find 3 different colors.

I've used red for may to june 11th. I also use red for non dated airstrikes elsewhere (Sumy, Lyman, Siversk).

Orange is for june 11th to july 11th, blue from july 11th to august 11th and finally yellow, just bellow. Image
