You just can't express it, really. Almost all the important bridges on the railroad and on the road corridors were knocked down. Ground transportation became difficult. Coastal and river transportation were blocked. Air superiority will be a requirement for sea control where a robust challenge from the air is possible.
Air supremacy is a necessary precondition of command of the sea.
Airpower is the decisive arm so far, and I expect it will be the decisive arm into the end of the campaign, even if ground forces and amphibious forces are added to the equation. If anything, I expect airpower to be even more decisive in the days and weeks ahead. None of my troops would get near a tank at night, because they just kept blowing up. Only one soldier was killed and two were wounded. The planes hit only vehicles and equipment.
