Subsequently, drones appeared on the battlefield, which created a 40-kilometer kilzon on the front line. Meanwhile, Russian troops began to break through the pipes. Similar events took place in Israel when Hamas fighters hid in tunnels under gas. The focus gathered information about new features of war when the fighting moves from the surface underground. During the First World War, there was a case where the military conducted an operation underground.
More than a century ago, in 2017, the Battle of Messen took place, preparing for which British miners broke through the tunnel at a depth of 24-37 m and laid 26 mines and 454 tons of ammonia nitrate under the positions of the enemy. The possible number of dead German military - about 10 thousand, indicated in the British Encyclopedia. During the Second World War, jumpers were also arranged, but not so successful.
On the Ukrainian portal, you can find out, for example, the actions of the guerrillas that were in the catacombs near Odessa. What is the experience of the underworld of the early 21st century? Focus wrote about three cases where the units of the Armed Forces of the Russian Federation were pierced underground and went to the rear of the Armed Forces. 1 case - Avdiivka. The offensive of the Russian Federation on Avdiivka began in October-November 2023.
At the end of January 2024, the Russians made a pipe in the rear of the Armed Forces - in the southern suburbs near the Tsar Hunting Restaurant. After that, as the military correspondent Bogdani Miroshnikov explained, the situation changed. The Russians cut the positions of Ukrainian defenders, blocked logistics, and the soldiers had to break through with the support of 3 OSHBR. 2 cases - Sudzhi Kursk region. The incident with a pipe in Sudzh occurred in early March 2025.
On March 8, the General Staff of the Armed Forces published a video of special operations for the disposal of Russians who tried to get into the rear. Ukrainian intelligence found the enemy at the point where the soldiers of the Russian Federation gathered, rocket and artillery strikes. Subsequently, the Russian troops told that some of the soldiers of the Armed Forces of the Russian Federation, who survived after being in a gas pipe, were in a hospital with fatal diseases. 3 cases - Kupyansk.
The new attempt by the Russians to break down underground analysts of the Deepstate project was called "Pipe 3. 0". It turned out that the route had been from the estuary of the first across the Oskil River to the Radkivka district, and from there the Armed Forces of the Russian Federation moved on the northern outskirts of Kupyansk.
Meanwhile, the command of August 13 confirmed that the attempt was indeed: the Armed Forces were trying to get into Kupyansk through the pipeline, which went to the surface outside the city in the north. It is indicated that four pipelines are suitable for the outskirts. Three of them were damaged or flooded. The fourth is under the control of the Armed Forces, the statement of the General Staff is said.
The captive Russian Mikhail Stepanov said that the pipe had made about 13 km: 8 km - on scooters, the rest - on wooden wheelbarrows. 70 people got the exit, but most died from the impact of drones, mortars, grenade launchers, small arms of the Armed Forces. 4 Case-Video appeared on the network from Pokrovsk. The record was included in the Russian military, who made his way as a sewer collector.
However, it was not possible to verify the frames, so it is not clear when and where they made the record. The Israeli Defense Army had to resist the enemy, who was also underground. Focus wrote about the attack of Hamas fighters on the Israelites on October 7, 2023, after which the war in Gas began. It turned out that the militants arranged about 500 km of tunnels with concrete walls, weapons, ammunition, and hiding places underground.
In addition, the outputs of tunnels were often located inside civilian buildings. One of the moves was written by The Times of Israel: Tunnel Hamas ran at a depth of 50 m and had dimensions sufficient to travel the cars. In the winter of 2023-2024, the Israelis began special operations against Hamasiv in tunnels. The military did not detail the methods, but the media wrote that it was probably flooding, as the fighters of the tsakhal installed pumps for seawater.
Israeli military Igal Levin explained in a conversation with NV that there were already concepts of underworld and there is a discussion in the military environment. The expert named two methods that can be used underground. The first method is to block the underground pathways: closing the passage with barbed wire, concreting, partitions. The second method is the use of special drones. There are devices that can move underground - ride or fly.
Other models are able to drill the soil and are a kind of underground torpedoes. "This is still at the level of discussion, but it is known that they are developing this direction. They are not particularly advertised, but there are countries that are developing. Why is it relevant? Because they are well aware that the war goes underground. We see how Russians go underground constantly when there is such an opportunity," The focus has searched on the network a few drones used for work underground.
Some of the projects are civil, some are military. Drones for traffic in the rooster of the Rooster Israeli company Robotican-a hybrid drone that can roll or fly in limited spaces (in homes, tunnels). You can attach the combat part to the root, and the ABI is able to identify and track the desired goals and act even without the operator team. UAVs weighs 1.
6 kg, capable of carrying a pay load of 300 g, to work 60-90 min (30 min, hang for 12 min in the air), to keep in touch through the Healing mesh system (several Wi-Fi nodes). The drone of the Asio X Swiss company FlyBotix - a device hidden in a cage that protects it from damage, has powerful lanterns and can carry measuring equipment for tunnels.
Drone toda to the Japanese company toda construct - UAV based on the AI, which explores tunnels, is able to bypass obstacles during flight (walls, equipment, people). Fly -Elios Dron from Flyability - used in mines for the extraction of palladium in the United States. The device conducted several missions at the mine to Lac Des Iles near Tander Bay, Ontario: He worked without light and in the absence of GPS, told the company's website. The task of the drone is mapping and tunnels.
Drones for drilling tunnels for drilling tunnels on the network found only two mention of development, which worked 10-15 years ago, and about the idea of 2022. Embur (Emerita Burrowing Robot) is a robot that deepeces the ground as an example of crab: he was told in 2022 by the developers of the University of California in Berkel. Researchers have explained that the device can take soil samples on land, at sea and even on the moon or Mars.
Unmanned Autonomous Burrowing Vehicle - a project was created at Affea's Engineering College in Israel, told on Militation portal. The developers have explained that the device is able to drill the breed and has a diamond cutter. It can be used to lay tunnels and lay out explosives for military purposes: however, it was only a prototype. In the video that appeared in 2014, we see a device similar to a storm that crashes into the sand.
Robotic Underground Munition (RUM) - the order for the development of the device was made by the US Defense Ministry Development Agency in 2010, wrote on the Defense One. The idea was that the device would have to do a soft landing from the plane and move underground. Information about what ended the idea was not found. Ukrainian developers have not yet shown models of drones that could work underground. Instead, the military command reacted to massive rocket-aromic blows that threaten personnel.
In particular, in September 2025, the Commander -in -Chief of the Armed Forces Oleksandr Sirsky reported that underground bins will be built on the territory of military training centers, in which the soldiers will study and live. In addition, the landfills will erect fortified armor, in which you can hide from the air attack of the Russian Federation.
It should be noted that on Facebook you can find photos of underground centers, published by the head of the educational and instructor group of the 151st NC of the Armed Forces of Ukraine Roman Donik. We see spacious rooms with high ceilings: bedrooms with two -storey beds, classes with desks and tables, lighting, various equipment. Civil authorities also responded to rocket threats.
For example, in the spring of 2024, the El Mundo media reported that Ukraine plans to develop the military industry and build underground plants. The developers of Ukraine and the world have not yet officially shown specialized military drones that could perform tuelings in tunnels and pipes, with problematic communication and without operating operator. Meanwhile, three cases were recorded in the Russian-Ukrainian war when the fighting was moved underground.
