The first footage has emerged of one of the Ukrainian army's underground bases. The exact location has not been disclosed, but the base is used by airborne units. The underground base is quite large, with corridors at least 400 meters long. It can accommodate up to six vehicles, including trucks. The base has a kitchen, storage areas, and other utility rooms. A permanent kennel for the unit's dog has also been installed on the base grounds. Warning signs have been posted on the pillars supporting the vaults, warning that using mobile phones may attract the attention of bombers.
