Here are som Placemarks and Overlays from the training in the States and England and the Normandy campaign.
Please comment if you think something is wrong or want to add something. I'm not an expert so I might well have got something wrong.

Check the overlays checkbox for some extra maps.

Edit:
I added Brecourt Manor. Thanks Munden for this post. See www.brecourtassault.com for more detail.
Started adding some placemarks for the Market Garden campaign.
