@SS-GEN WOW! so it doesn’t matter how many planes are there. only how many Artillery pieces. I have been playing it wrong! Thanks :)
Rules say:
“Shoot Down Air Units: Artillery can shoot down attacking air units. Whenever an order card so directs, each artillery
can fire on one air unit in its zone. Roll one die per artillery against an air unit: On a roll of 1, that air unit is destroyed.” AN air unit. not EACH air unit.
