I think they can find the entrance from IR viewing. If the entrance is in a building maybe not.
If tunnels are located they can be destroyed. The Russians hit a facility in Ukraine command post 400 meters below the ground.
It is quite likely Israel has the same types of bombs/missiles as does Russia.
I’m not buying a bomb/missile burrowing 1,200’ underground.
But while you’re hanging out... check out this groovy tune!
