Hey all, my local is arranging a large display game for the near future using black powder and the American players have been curious as to rank depths for Americans, 2 is obviously the standard depth for the rules, but from a visual perspective only would using 3 or more ranks in depth have any historical backing?, either in unit structure, training etc, allot like how the Nap French fought in 3 ranks.
This is simply for visual appeal, so don't worry about rules clashing with the added depth.
