Tanks /Pol bro.
Any clear signal on /Pol last few hours?
Good sapper team uses RV to hide access to manholes and street lift.
Pack conduits, and drill holes through concrete to interior. Pack 12" drill holes with ANFO And cap outside end.
Fill under street with with proper stochiometric max ratio to have sewer area conflagration/explosion (special effects), maybe some gasoline containers and det. cord.
They had some 24 hrs to plant it. No need for nukes or risky aircraft drone etc drops.
You guys don't have a clue what demo teams with time and simple explosives can do.
