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.

The use of unmanned ground vehicles (UGVs): the new revolution in the Ukrainian 🇺🇦 war.

Replacing infantry, UGVs fulfill several roles: combat support, troop evacuation, mine-laying, or logistics...

The revolution of ground drones in Ukraine 🇺🇦/🇷🇺 :

🧵THREAD🧵1/17⬇️Image
Like images from the future, ground drones are becoming increasingly visible on the ground in Ukraine.

While the arrival of aerial drones and their variants, as well as naval drones, has been well covered, the arrival of ground drones has been almost forgotten.
Multiple videos from the last few weeks are showing a wider use of ground drones for various missions.

Even if they are often targeter by aerial drones, they are still being very useful.

Les fortifications peuvent-elles changer le cours de la guerre en faveur de l'Ukraine 🇺🇦 ?

Malgré un manque cruel d'infanterie pour les occuper, les obstacles ukrainiens sont de plus en plus nombreux et conséquents, ralentissant la progression russe 🇷🇺

🧵THREAD🧵1/23 ⬇️Image
Cela fait plus de 3 ans que j'analyse régulièrement la question des lignes de défense en Ukraine.

J'ai cartographié la quasi-totalité de ces défenses, analysé leurs résultats, leurs échecs et les récentes évolutions. Image
D'abord avec cette carte, vous pouvez voir en rouge les fortifications creusées en 2025 et en vert le territoire pris par l'armée russe la même année.

Pour la première fois, nous allons le voir, ces fortifications sont continues, bien préparées et nombreuses. Image

We often talk about russian 🇷🇺 losses but little about ukrainian 🇺🇦 ones

Holding into Myrnohrad and continuing to send troops inside Pokrovsk has proven to be very costly.

A small update on Pokrovsk, the strategic front and "peace talks" :

🧵THREAD🧵1/12 ⬇️
Russian soldiers have been seen throughout the city of Pokrovsk for 1 month and half.

According to my research, they still control the majority of the city and are continuing their consolidation. The area south of the railway is +/- under Russian control. (old map) Image
The main area of ​​interest is further east. As the video in the first tweet shows, dozens of Ukrainian armored vehicles and pickup trucks were destroyed on the Rodynske-Myrnohrad road. In Myrnohrad, the Ukrainians still control most of the city. Image

Poland 🇵🇱 started the construction of part of its "eastern shield" on the border with Kaliningrad 🇷🇺.

After 4 years of war in Ukraine, Poland and the Baltic states are however barely starting to prepare defensive lines on their eastern borders...

🧵THREAD🧵1/10 ⬇️ Image
It should already be a reality, it is however still a plan.

After announcing they would prepare fortifications on their eastern border, Poland, the Baltic countries and Finland barely started to build them. The area is only covered by anti-migrants barricades. Image
For now, I only found 3 small areas where we can see fortifications, all in Poland, on the border with Kaliningrad, a Russia oblast.

On the eastern border of the EU, we can only see preparations for fortifications and road blocks on the borders. Image

Cette vidéo des forces ukrainiennes 🇺🇦 a bientôt 4 ans, plus jamais nous ne verrons ce type d'image.

Pourtant, bon nombre d'armée occidentales fonctionnent encore comme si la guerre en Ukraine n'avait pas lieu.

Il est URGENT de se mettre à jour :

🧵THREAD🧵1/22 ⬇️
Les armées ukrainiennes et russes ont un avantage technologique massif sur les armées occidentales. Les leçons apprises d'Ukraine seront importantes à prendre en compte ailleurs.

Sommaire :
-drones
-pertes
-blindés
-tranchées
-déploiement de troupes
1- Le drone de reconnaissance

L'utilité principale du drone étant la reconnaissance, celle-ci est massivement utilisée. C'est une chose que nos armées commencent à bien intégrer.

Aucune unité ukrainienne ou russe n'est sans moyen de reconnaissance. Image
