Have started playing around with Muskets and Mohawks for Napoleonics. Some changes are required as Muskets and Mohawks is written with each unit being a company. The Napoleonic version moves up a notch to the more traditional battalion, battery, regiment scale.
This requires some changes in mechanics, ranges and so on. More significant changes are required in the solo/coop campaigns and if you will, AI.
All told a "division" comes out to about 60 infantry, and one gun with 6-8 crew. Naturally either side may be augmented by reinforcement over the course of play.
Early days yet but so far so good.
