Were the names given by the Allies adopted? Are the beaches known formally or informally as Utah, Omaha, etc? What were the pre-war names? Do those beaches have any other claim to fame? Are there any other cool facts about the beaches you can share?

My apologies if this is topic already covered.
I gave the search feature my best shot and came up dry.

(This question is fueled by my recent (re)watching of Band of Brothers)
