I emailed the author Michael to make enquiries. I ordered these two scenario booklets, which can be used for any set of rules, so very flexible. Some of the scenarios are of quite niche battles but they’re all well presented with maps, orders of battle and players’ notes.
They arrived about a week later, which is pretty good from Canada, but I was also emailed all the maps and scenario notes/orders of battle, including a couple of scenarios not included in either book.
