In order to stop Ukraine's **, Russia has placed a large number of mines in the frontline area, which has brought great difficulties to both sides in the operation. According to U.S. intelligence sources, the Russian army has planted at least 1 million to 5 million mines of different types, including ordinary mines, butterfly mines, anti-tank mines and auto-triggered mines. These mines significantly reduced the speed of the Ukrainian army's offensive and caused a heavy **.
In order to support the Ukrainian army, the US military has provided Ukraine with a variety of minesweepers and anti-mine armored vehicles. But these vehicles also have drawbacks, and the convoys they form on the roads are easily detected and shelled by Russian drones. And the Russian army is not without worries, they also have to be careful of the mines they have planted when they are **. In addition, the infiltration team of the Ukrainian army also set up a large number of blasting bombs and mines on the communication lines of the Russian army, interfering with the logistics supply of the Russian army.
In order to solve the problem of these mines, the Russian army began a "large mine sweeping" operation. They used the armored train "Yenisei" of the ** Military District to clear more than 3,000 kilometers of unexploded ordnance from railways in the zone of the special military operation. This armored train is a special transport of the Soviet era with great protection and firepower. They escorted more than 120 military trains and transported large quantities of supplies. The railroad corps also repaired seven small and medium-sized bridges and restored traffic on these sections of the railway.
According to RIA Novosti, Russia's ** operation has already begun. Compared to the mine clearance operation in Ukraine, the Russian army appears to be more resilient and efficient, and they do not care much about the problem of landmines. If Ukraine wants to break through the defense line of the Russian army, it must find a new solution, otherwise their ** will remain in a stalemate. There are comments that Ukraine needs more advanced demining from Western countries**, but Western countries may be reluctant to do so.
