Love the rules, especially the officers and their honour and traits. I think that builds an excellent narrative which the scenarios you've included also help form.
I'm loooking at winding them back to the mid to late 1500's though. Earlier handguns etc will become commanded shot (looser, smaller and less formal and more mobile than formal ranks of matchlock muskets), zweihanders, halberdiers and enfants perdue and possibly swordsmen will become forlorn hope, (their job is to break the pike block, and this also represents loose bands of marauders). Gendarmes will elite gallopers - due to their armour as suggested in the rules, mounted arquebus and crossbow as dragoons - as the can skirmish and mount and dismount. Later pistoliers will be trotters and Demi lancers and cuirassier become gallopers.
It will be a while before I get to put figures down on the table to tast these ideas and they are all just outline thoughts at the moment.
Looking forward to giving them a go in any case. Congrats on an excellent set of rules!
