how do you do an air strike on unconditional surrender - when i click on an air fighter it gives option to move it - dont see option for doing an air strike:
6.2.2 Air Strike
A phasing fighter or bomber unit in a hex can activate to attack an
enemy air or naval unit within a 7-hex range of the phasing air unit.

First:
- Please post these sort of question on dedicated forum: https://boardgamearena.com/forum/viewforum.php?f=316

Second:
- If some air/naval units are in range to be attacked by air strike, you will have them in a dialog popup.
- If you have no dialog popup, none are in range.
