He further went on to observe
"Here is where I appreciate the aviation units in the Cav...when the weather is good.

Which takes me to:
- How well have Ukraine established local air superiority in the vicinity of the breakthrough" ... and ...
- How well have Ukraine established EW spectrum dominance / superiority in the area (let's say 10-20 nm radius) around the breakthrough?
- For Ukraine to exploit this they need to be able to spoil and/ or stall various counterattacks. More importantly to interfere with the sensor-to-shooter links between local Russian forces and Russian artillery.
