@Gamerman01:
Because I don’t know what in the world the sentence on page 32 is talking about exactly, you will have to wait for Krieghund for the authoritative answer on this.
If a carrier doesn’t work to overcome the sub block, then he has some explaining to do about page 16.
Well it kind of makes sense if you look at page 15
Aircraft Carriers
Although they don’t have an attack value and aren’t
represented on the battle strip, carriers can still participate
in an attack and can take hits, as long at least 1 unit with
an attack value attacks along with them.
Carriers are NOT allowed to attack unless they’re accompanied by at least 1 unit with attack power, since subs can’t be hit by air you could make the argument that fighters don’t have an attack power in that situation.
Also, in the convoy raiding section, it says any warship in a convoy zone and then it goes on to actually specify that carriers are excluded. So it starts broad and then gets specific.
