Normandy 44 Bunkers

[Sgt Barker]

Now another specific I would like is some LIMIT ON STACKING in the pillboxes in general not just Omaha.

I doubt this is technically possible. There no other example I can think of where the same type of unit is treated differently in a hex depending on how many are stacked there.

IMO looking at a "bunker" for example as a single, or even multiple pieces of terrain is a mistake. A "bunker" is not literally a bunker, or even more than one bunker. It is simply a name for a gradient of defensive works between TRENCH and BUNKER that covers an entire 1km hex.

With 8 levels of fortification available the answer to making Omaha easier for the allies to exit is to simply dink around with setting different levels of existing fortification for each hex (which is exactly what VM looks to have done). From "improved" to "PILLBOX", just edit away until the right mix for the half dozen or so hexes are found.
