« The Donbass Line🇺🇦 »

Since 2014, 2022 and more recently winter 2023, Ukraine has been building a huge defensive system. The multilayered “Donbass Line” composed of many trench network is quite similar to Russian Surovikin system.

🧵THREAD on Ukrainian in depth defenses⬇️
1/25 Image
When we talk of defensive trench network, the huge Surovikin line is the first thing we think about: trenches, bunkers, mines, dragon teeths…

This particular system, sometimes compared to the Maginot line was one of the assets that stopped Ukrainian summer counteroffensive.

2/ Image
Since it is already mapped by many, it is not useful to talk about it.
However, I’ve also mapped pre-2022 Russian defenses. It is interesting to see that these particular trenches system can still be used in case of a Ukrainian breakthrough.

3/ Image
Let’s talk about Ukrainian defensive lines I called “Donbass line”.

Donbass line is quite different and more complex than Russian Surovikin system: it is composed of highly defended fortified system, separated by fields.

Zoom in⬇️
4/ Image
If we take the example of Ukrainsk-Muraka line (facing south near Kourakhove), we can see on this Sentinel-2 imagery that each system is separated by a kilometer at least.
Each fort can defend itself from every direction: you have to take all of them to advance.

5/ Image
Contrary to Russian line, Ukrainian one is composed of many forts that are defending each other.
The 2014-15 Popasna-Luhanske line is a good example: to breakthrough, you have to assure that no other fort has fire control on you. (This particular line was however abandoned)

6/ Image
The line 0:
This was the 2014-2022 line, it was composed of 2 systems near Marioupol (overrun in a few days because of the lack of personal), 2 lines near Popasna (Ukr retreated to the city) and one line between Marinka and Horlivka, with some part still standing.

The really first line built from February to June 2022, preparing the retreat of Sievierodonetsk was built from southern Bakhmout to Siversk, passing through Soledar
This defensive system had 2 lines, both were overrun in Bakhmout and Soledar but are still standing in Siversk.
8/ Image
At the same time, Ukrainians built lines 1, 2 and 3 in northern Donbass. Today, they are still building these lines.
Line one: Siverski-Donets river/Tchasiv Yar/Toretsk.
9/ Image
Line two and three are the defenses of Kramatorsk and Sloviansk: 2 lines are protecting Sloviansk from the North, an anti tank ditcj and 1 line protecting the twin cities from the west.
+ 2 lines protecting Kostiantinivka/Droujkivka.

10/ Image
Now, as some may ask themselves, the defenses after Avdiivka are already prepared but non-sufficient: main line is 17km from the city.
This line is however behind a river and lakes, making it a natural barrier.

11/ Image
The final objective of the Russian offensive may be to reach Pokrovsk, the last big city and industrial center of Ukrainian Donbass (with Kramatorsk).
The Ukrainian Armed Forces have built a two layered trench system all around the city.
13/ Image
Support lines:
Donbass is a thing, but there are 3 other fronts: Kherson, South (Zaporijia) and Louhansk/Kharkiv.

Apart from Mykolaiv defense network and old Russian Kherson defenses, I haven’t found any Ukrainian line in the oblast.
14/ Image
In Zaporijia oblast, there are at least 2 main defensive lines, plus a line defending the city itself. In Louhansk frontline, we have the Lyman-Borova line quite impressive. There is also a line near Izioum.

15/ Image
Currently, I’m investigating Ukrainian defenses on Russian border: the Koupiansk-Vovtchansk line, the Kharkiv defenses and border defenses in Sumy and Tchernihiv oblast.
For now I havn’t find many things, suggesting it is just the beginning.

16/ Image
How does those systems look like? This image is a high resolution one (from google earth pro): you can see part of the western Sloviansk defense.
A Ukrainian trench is never linear, and it is not always linked to avoid loosing a whole line if one part has fallen.

17/ Image
Ukrainians made fun of Russian anti-tank ditches and dragon teeths, but they are now using it. You can also see this new basement to protect soldiers from artillery and FPV shells.

To geolocalise these trench network, I used 4 elements:
-Google earth updates (from June to august 2022)
-Sentinel-2 imageries, most of them until may-july 2022 (since it is the best time to see trenches)
-Geolocated Videos showing trenches (Kreminna forest)
-Esri Imageries

Since some may ask, this work is not helping Russia. Why?
-We mapped Russian positions and defenses before
-Russia has satellites, and IA that can detect these lines
-For most of it, it is now nearly 6-month-old
-The map is indicative and non-exhaustive

20/
I’ve been mapping Ukrainian and Russian defensive lines since nearly 2 years, this is the first part of my final project, it will be updated and improved many times in a row.
Here is the link to have it on your computer. Please credit me when using it!
21/google.com/maps/d/edit?mi…
Keep in mind that when I’m using Sentinel-2, I can’t be precise, and there may be errors since it is sometime really difficult to know if there is a trench or not.

I will improve the map with updates of Maxar imageries in Google Earth.

22/
Here you can find the link for my interpretation of the lines. Since it is not a continuous defensive system, it is only an interpretation of hundreds of trenches. As tweet #21, you can download both trenches and defensive lines.

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

Quelles solutions pour l'Arménie 🇦🇲 ?

Comme ce tweet fait réagir, je vous propose un retour historique, contextuel, et actuel sur la situation de l'Arménie.

Seule, isolée et oubliée, l'Arménie a les cartes en mains pour son futur, si elle choisit la paix.

🧵THREAD🧵1/26 ⬇️Image
D'abord, l'aspect géographique :

🇦🇲Arménie : 29 743 km², 2,97 millions d'habitants, PIB de 24 milliards USD.
🇦🇿Azerbaïdjan : 86 600 km², 10.11 millions d'habitants, PIB de 72,36 milliards USD.
🇬🇪Géorgie : 69 700 km², 3,91 millions, PIB de 35,35 milliards USD. Image
L'Arménie est le plus petit, le moins peuplé et le plus pauvre des 3 Etats du Caucase, sans accès à la mer, sans ressources naturelles.

L'Azerbaïdjan est 3 fois plus grand, 3.4 fois plus peuplé et 3 fois plus riche que l'Arménie, qui ne dépasse que pour le PIB par habitants. Image

Du Mali 🇲🇱 au Soudan 🇸🇩, le Sahel décomposé

Sur les 6 Etats Sahéliens, 5 sont en Etat de guerre, dont 3 contrôlant moins de la moitié de leur territoire national.

Rébellion de l'Azawad, groupes terroristes et guerre soudanaise, la région en pleine implosion.

🧵THREAD🧵1/24 ⬇️Image
Le Sahel se résume généralement à 6 nations principales, la Mauritanie, le Mali, le Burkina Faso, le Niger, le Tchad et le Soudan.

Le plus stable actuellement est la Mauritanie, suivie par le Tchad (l'insurrection djihadiste ne touche que le sud-ouest, au bord du lac Tchad). Image
Au Soudan 🇸🇩, une guerre civile oppose depuis le 15 avril 2023 deux "armées", les Forces de Soutien Rapide, groupe paramilitaire rebelle dirigé par Hemetti et composé des arabes du Darfour et l'Armée Soudanaise régulière, dirigée par Burhan et composée des arabes du Nil + alliés. Image

L'armée ukrainienne 🇺🇦 a lancé une série de contre-attaques locales dans la région de Pokrovsk.

Dans le même temps, la zone grise continue de s'étendre et l'aviation russe 🇷🇺 bombarde massivement la zone, plus de 430 nouveaux impacts de FAB recensés.

🧵THREAD🧵1/24 ⬇️Image
Nous avons désormais tous les éléments pour confirmer l'infiltration en profondeur de soldats russes dans l'axe de Dobropilla il y a deux semaines.

Les vidéos montrent que les soldats russes étaient présent à Pétrivka, 20km de la ligne de front connue et 15km de la zone grise.
Minimiser la chose ne change en rien la réalité : les russes ont profité d'un trou entre deux unités mais n'ont pas été en mesure de l'exploiter, pourquoi ?

-Réaction rapide des ukrainiens
-Pas de logistique autre que des hommes à pieds
-Extension des lignes trop en profondeur
-Impossibilité d'acheminer des renforts face à la couverture de drones, l'absence d'abris, la présence d'obstacles et le faible nombre de passages dans ceux-ci.Image
