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.

Depuis un an, le front ukrainien a doublé de longueur, passant de 800km (dont 300 faiblement actifs le long du Dniepr) à 1 600 km

C'est le résultat des incursions prolongées à la frontière russo 🇷🇺-ukrainienne 🇺🇦, à Kharkiv et Sumy.

🧵THREAD🧵1/23 ⬇️Image
Au printemps 2023, successivement à Briansk et Belgorod, l'armée ukrainienne avait lancé via des groupes de russes anti-Poutine des opérations transfrontalières de faible ampleur, pour la première fois depuis le retrait russe du Nord et Nord-Est de l'Ukraine en mai 2022.
Ces incursions se sont poursuivies au printemps 2024, mais elles ont été stoppées par les pertes importantes et la fortification de la frontière côté russe.

En réponse, Moscou a créé le corps "North/Sever" visant à mener des incursions transfrontalières en Ukraine.

Les images satellites Sentinel-2 du jour couvrent une vaste part de la ligne de front 🇺🇦/🇷🇺 active et donnent d'importants indicateurs.

-> L'armée ukrainienne creuse des tranchées à très grande vitesse
-> L'arrivée de l'été ouvre la porte aux feux tactiques.

🧵THREAD🧵1/11⬇️ Image
En l'espace de 10 jours, un fossé anti-char entier a été creusé au nord-ouest de Sloviansk, on parle de 20km de fossé, une cadence qui tranche avec la précédente lenteur de la préparation des fortifications.
Comme je l'ai démontré hier en anglais, l'armée ukrainienne met au point sa nouvelle ligne de défense du Donbass, à l'ouest de la région et des principales villes.

Rien que sur cette photo, j'ai aujourd'hui ajouté une quinzaine de nouvelles tranchées. Image

In May 2025, the Russian 🇷🇺 army achieved record advance in Ukraine 🇺🇦 and started faster in June

In Sumy, Lyman and in the south of Donetsk oblast, Moscow pushed back and isolated several fronts, but key cities are not yet threatened.

🧵THREAD🧵1/23⬇️Image
On this beautiful map made by @Pouletvolant3, we can see how much Russia progressed each month of 2025 in Ukraine.

We can see 4 main directions, Kursk and Sumy, Lyman, Kostiantynivka and south of Pokrovsk. Image
To this chart, we can add this one by @Deepstate_UA showing that the month of may 2025 is the 3rd biggest in the last year and half.

We can note the february-march pause that I previously highlighted and the start of the new offensive in late april. Image

En frappant ~30 bombardiers stratégiques de l'armée russe 🇷🇺 depuis le territoire russe, le SBU ukrainien 🇺🇦 signe une opération réussie.

Cette opération aura-t-elle une incidence dans la guerre ? C'est à cette question que je vais essayer de répondre.

🧵THREAD🧵1/24 ⬇️
Depuis des mois, le SBU ukrainien préparait une opération secrète d'ampleur sur le territoire russe, nommée « toile d’araignée ».

Contrairement aux précédentes opérations, les drones ne sont pas partis d'Ukraine, mais bien de Russie.
Pendant des mois, les espions ukrainiens ont créé de toute pièce une entreprise de maisons préfabriquées à Tcheliabinsk, au cœur de la Russie.

Ils ont créé de véritables commandes et préparés des transporteurs. Image

« Putin 🇷🇺 decided to withdraw his forces from Kyiv, Chernihiv, Zhytomyr and Sumy Oblasts as a good will gesture on March 31 (2022)»

@AMK_Mapping_ supposedly "realistic pro-🇺🇦 account" fell again for russian propaganda.

But this time, he is spreading lies.

🧵THREAD🧵1/24 ⬇️
On February 2022, Russian army launched a total of 11 armies to establish the Novorossia project (annex Kharkiv, Donetsk, Luhansk, Zaporizhia, Kherson, Mykolaiv and Odessa oblasts + maybe Poltava and Dnipro) and change the ukrainian government for western Ukraine in Kyiv.Image
AMK states that

1. Putin invaded a country of 560,000km² with ~190,000 troops.
2. Most of these soldiers weren't even deployed in Kyiv Oblast.

He is right, but misunderstand nearly everything. Image

Au printemps 2023, l'armée ukrainienne 🇺🇦 met au point un plan de contre-offensive.

Ce plan entrera en action en juin 2023, au sud de l'Ukraine, pourtant, les russes 🇷🇺 savaient déjà tout et ont pu déjouer l'offensive dans les premières heures.

🧵THREAD🧵1/25 ⬇️ Image
Elle est annoncée en grande pompe, dès l'hiver 2023. La grande offensive du printemps 2023 doit permettre de libérer les territoires occupés par la Russie.

A ce moment, une partie importante de l'armée ukrainienne combattante est embourbée dans l'attrition de Bakhmout. Image
Une autre majeure partie de l'armée ukrainienne est en formation, principalement en occident et dans l'ouest ukrainien, prenant rapidement en main les nouveaux équipements.

A Kyiv, dans le plus grand secret, les plans d'offensive sont préparés. Image
