Artillery with air support

[Anzac defender]

Im a bit confused with the artillery and air support that hits on a 4. If i have 4 artillery and 1 plane does all 4 artillery attack (roll 4 dice) or 1 artillery attacks and the other 3 hit as a 3?

All 4 roll at 4.

Does same go infrantry and artillery,  8 inf and 3 art, all 8 infrantry attack on a 3, or only 3 infrantry attack and the other 5 attack as a 2?

Artillery pair up with infantry, the inf roll at 3s for each arty they get paired with.

If you have air superiority all artillery roll at 4 as long as you have at least one fighter. Fighters still roll at 2.
