I probably don't understand your question at all, but famous (and fictional) battle of Ouistreham Casino was recorded in the real city called Port en Bessin. FH2 map is a slightly scalled down real place, it is the battle of Port en Bessin, not a movie tribute. All the buildings are where they should be, hence there are no fictional locations from the movie set.
You can compare FH2 map to a real place,
