Ancient Battles Deluxe : Expansion Kit 3 Ordinance

From the Publisher's website:

Added to the stench of battle is a foul new reek, the stink of sulfur! Now small formations of light gunners armed with the early arquebus, and heavier formations of coronelias and tercios can lay fire across the field of battle. But they are not alone, for early cannon such as the culverin, clumsy as they are, have also been introduced. Now as these strange ordnance add a thick smoke to the battlefield and hasten the twilight of ancient battle tactics.
