Russian invaders are building a new line of defense that stretches from the village of Nikolske in the Mariupol district to the city of Berdiansk in the Zaporizhzhia region.

Petro Andriushchenko, adviser to the mayor of Mariupol, reported on this.

According to him, invaders started building fortifications from Nikolske towards the village of Starodubivka and further towards Berdiansk.

Despite the fact that it is about 50-70 km to the front, invaders continue to build fortifications and defense lines.

To do this, they are actively building a line using anti-tank obstacles, better known as “dragon’s teeth.”

“Dragon’s teeth” are used to create obstacles for tanks and mechanized units. In addition, when vehicles run into them, there is a high probability of damage to the bottom.

According to local residents, Russian invaders are also actively bringing wood to these areas to create dugouts.

In addition, invaders created a kind of defense line from railroad cars. It stretches along the railroad track from the railway station in Olenivka to Volnovakha.

It is 30 kilometers long and consists of about 2,100 railroad cars of various types.

The construction of this massive defense line reportedly began in July 2023. It was apparently built using rolling stock stolen from the temporarily occupied territories.

Such a defensive structure, which is actually a solid wall, is a very serious obstacle on the way of advancing troops.

Given that some sections of the railroad track are built with a high subgrade (an embankment that distributes the load on the ground), this line of defense is a full-fledged defensive rampart.
