Sure, I had 2 full Air Force Attack and Bombing units and another 2 full Air Force Attack units and two full Long Range Division.
First I've used the 4 Air units (except bombers) to destroy the C3 air force units; Second I used the 2 Attack and Bombing (with bombers) to destroy the land based units and the military installations (bases and airports).
Finally, I've used the air units (the ones that still had some ammunition left) to seize the garrisons of the fortifications, main cities and factories I needed to destroy. Finally, used the land unit to conquer it all. Used huge ammounts of bombs, air-to-air missiles, helic-attack missiles, drone missiles. In the final stage also got out of tank and artillery ammunition. Every attack I've tried to calculate and reduce the number of weapons I was sending to the attack but I am not sure it made a big difference.
