The AFU has been controlling these tunnels for a long time. Do you really believe that they have not been preparing demolition charges to collapse the entrances and exits to this whole complex in case they have to evacuate? If the Russians ever enter these places, “The Walls will Come Tumbling Down”.

They aren’t going to enter. That would be foolish.
They will methodically seal all the exists. Then fill the tunnels with gasoline...or some other vaporized accelerants.
