User summary: Advance The Colors is the first widely-published set of 1:1 ratio rules to cover the American Civil War. The rules focus on simulating tactical and skirmish-level engagements between company or regimental-sized units with an ideal size limit of between 200-300 figures per side. Each miniature represents a single soldier or artillery piece and the rules provide for officer ranks, command and control, and campaign development of individual soldiers through heroic actions. The rules we're written primarly for 15mm miniatures but can easily be used with 5mm-25mm.
