I understand that without a destroyer any attacking air units cannot hit submarines. Which also means as a defender I cannot assign hits from air units to submarines.
Isn’t this a huge drawback if I, for example, use submarines to soak up damage in sea combat but would be unable to do so if the opponent doesn’t have any destroyers and therefor I would have to assign hits to more valuable units?
The destroyers ability to make my subs visible should be a drawback. Why can’t the defender just order the subs to surface? From a tactical point of view this just makes no sense to me.
