Hello! Some quick things about Warlords of Erehwon:
There are order dice but the bundles do not come with them. This is based on Gates of Antares and by extension based on Bolt Action so it have the unique activation system of those games. You can use Bolt Action Order Dice or chips or whatever for the activation bag. Otherwise the game uses D10s for the gameplay.
The units are like BA or GoA where each figure represents one soldier but they move and fight as a squad. Squad sizes will vary based on which faction you play and how many points you have available. Generally this has been given to be 5-10 models per squad. I have seen on the Facebook page two examples of 400 pt armies which are considered to be a small force. games of around 1000 pts will be common and 2000 pt battles are definitely possible.
