UAF demonstrated the construction of defensive fortifications in Donetsk region started back in 2023
Since the end of 2023, including the period before and after the withdrawal from Avdiivka, the construction of defensive structures to strengthen the front lines has been underway in the Donetsk region

Since the end of 2023, the Donetsk region has seen the intensive construction of defensive structures, the activity did not decrease even after the Ukrainian forces retreated from Avdiivka.
Dmytro Lykhovyi from the "Tavria" operational-strategic group shared on social networks photos of defensive constructions in the area of Avdiivka, including areas only two kilometers away from the site of combat encounters.
According to him, a large part of the fortifications is already completed, although some are still under construction.
The construction is carried out jointly by local administrations, private construction firms, the State Special Transport Service, as well as engineering and mechanized units of the Armed Forces of Ukraine.
Despite obstacles such as a shortage of labor, funding, materials, and weapons, difficulties related to the proximity to the front, bureaucratic barriers, and issues of land ownership, concrete achievements are visible.
These fortifications can be seen; they provide protection from shelling, emphasized Lykhovyi.
He pointed out that the fortification work began in December last year and intensified after the troops withdrew from Avdiivka.
The defensive structures being erected in the Donetsk region are comprehensive support points of the second line of defense, intended for the regrouping of infantry.
Consisting of dozens of new points, these defensive structures include numerous trenches equipped for various angles of fire, as well as fortified positions, anti-tank ditches, and other protective elements.
Lykhovyi also noted that new standards require larger trench sizes — 2 meters in height and 1 meter in width, allowing soldiers to move standing up and evacuate the wounded without having to bend over.
