The rules are interesting. Not what I expected. There were a lot of people online in the run up asking about army sizes/basing as you do but the authors/publishers gave nothing away. Having skimmed them, there's nothing really to say as they scale up or down to whatever you want to use. Very generic system and very simple. So far I quite like them.
Its a good WSS issue this month too. Persian flavour with a Dunkirk scenario plus others and a Silver Bayonet review.
