Battlefield 1942, September 10, 2002:
The American players started on a battleship (which could be controlled and operated), and all players needed to board a landing-craft in order to get to the first objective (capturing the beach head).
And once you got there, the player driving the landing craft, opens the hatch and releases the other players on the beach.
Then there’s the beach itself, which appears more realistic than the D-Day map we have in Enlisted (not talking about the graphics, but the layout).
The objectives progress from the beach, up the hill (to the first defensive fortifications), and then another hill after that.
Axis tanks could fire downhill, onto the American’s below.
And there were a few bunkers with kill zones, for the axis defenders. (The Americans have player-controlled battleship/naval support)
Hey look, a giant cliff for the Americans to fight up (unlike what we have in Enlisted)
The battleship down below, which can be driven and steered further out to sea (it could be destroyed by axis artillery)
And then there’s Day of Defeat (Released May 1, 2003), which had a really fun D-Day/Omaha beach map (although, it was considerably smaller with matches composed of 16 vs 16 ).


Then there’s the later modded version
And then there’s Hell Let Loose, Omaha and Utah beach maps


So my suggestion for further development/optimization of the D-Day map, is to review historical images of what the actual battlefield looked like, and try your best to replicate the geography and defensive barriers/fortifications.
It’s clear that the consensus of the player-base wants the D-Day map entirely re-worked in a way that resembles what the actual invasion was like. In the game’s current state, with paratroopers hot-dropping ontop of bunkers, and the hillsides, and ontop of the objective… mixed with the absurd layout of the map. It looks nothing like D-Day. Especially the sunny blue sky, and nice weather. (anybody equip their soldiers with swimming shorts?)
And once the Merge happens, D-Day is gonna become an amusement park
