ACW Rules
These house rules are based around rules from the book One-Hour Wargames by Neil Thomas. They are for designed for play on a 6” gridded tabletop. However, the rules use the term ‘bound’ for a distance of 1 square, so If you prefer free movement convert each bound to a 6” distance for measuring.
