According to Ukrinform, this is reported on Facebook by the Main Intelligence Directorate of the Ministry of Defense of Ukraine.
During the operation "Barrel", the underground of the Legion "Freedom of Russia" managed to establish how the Russian Federation is trying to compensate for the losses suffered as a result of the defeat of oil refining and port infrastructure by the Defense Forces of Ukraine.
Due to the reduction in available tank capacity, the Russians began to look for other ways to store and move oil raw materials. One of these solutions was the dispersed transportation of oil by rail — in tank cars on the territory of the Russian Federation.
This method of logistics has become a new target for the resistance movement.
The operation was preceded by a long preparation and complex work of the underground. It is about penetrating into the relevant hostile structures, obtaining classified information, their further analysis and establishing vulnerabilities in Russian logistics.
