I took these from the MOVEMENT.INI file from the Iceland02 terrain folder. That will get you up and running.
There is till something bit odd going on with the unit entries. Unfortunately, I don't have time to look into it just now.
Try using this as a template campaign for the Iceland02 terrain. You will need to swap out some of the unit types, as some of those old mods I used are no longer available for one reason or another, or have been superseded by updated versions.
