The Perfect Captain offers “Red Actions”, another in their series of superb free wargames rules. This particular set is designed for miniature wargames in the Russian Civil War. Like all of the Captain’s rules, these have superb graphics — but they are not just gratituous pictures. The thing that makes these rules so special is how tightly the graphics are integrated into the game system.
Bob Bergman has written a set of free wargames rules for the American Civil War called Seeing The Elephant. Designed for two different regimental and a brigade scale, the rules use a card activation mechanism, combined with a Morale Check. Firing is done by adding Fire Factors and rolling a die; Melee by figuring odds and rolling a die. In all, a comprehensive, well-thought out set of rules.
