Playing a game with my kids, I ran into a scenario where the rules are not well defined; I think.
Assume an aircraft carrier has launched its planes into an amphibious landing. Now, the defender scrambles a fighter against the landing fleeting. The combat value of the fighter is 4. But what is the combat value of the aircraft carrier?
Interpretation A: zero, because the aircraft carrier is attacking. It can take hits, but its combat value is zero.
Interpretation B: two. It is being attacked, and so, it should use its defense value.
So which is it? zero or two?
