can a bomber :
1. attack one place more than once on a turn?
2. attack more than one place on a turn…ie bomb one country then bomb another ect
so tanks or infantry can attack more than once per turn but planes can not?
All units can be used for only 1 battle per turn.
However, they can fight as many rounds of combat as needed in that battle in that one territory or sea zone.
