Wow. Looks amazing. Can't wait to see thevresults.
Likewise
Jon always does great AAR, ditto campaigns. I ran this a few years ago using BP or HoW (I can't remember which!) and some of the 'scenarios' worked well, others less so. Jon's increasing both sides forces should help a lot to ameliorate these issues.
That looks cool, I'm going to link to the FB group as well as mention it in a video.
