@P@nther:
Just read the FAQ carefully. The scenarios are different.
Subs can never hit planes.
I think you refer to a case, where a fighter and a destroyer attack a sub and a cruiser. Here both hits can (and must) be assigned legally. Sub hits destroyer and cruiser hits fighter.In the above scenario there is only one hit that can be legally assigned - as subs never can hit planes.
Ah, I see.
