Thanks to both of you!
In terms of positioning, no, there are no troop movements per se. However, you may have population movements between cities, and you may have military fortifications increasing or decreasing along a line of demarcation, which is basically the same thing. It's tricky to explain, but I think it's really easy when you see it in practice. Knock on wood.
I look forward to being able to show it off in some videos, probably in January.
