Bloody Red Flag provides advanced & supplemental rules for the Close Action naval wargame. The supplemental rules are an integrated set designed to simulate tactical naval warfare in the late sail era in a more realistic manner than Close Action permits, but at the cost of some additional complexity.
The primary change in Bloody Red Flag is the implementation of a 12-point movement system to replace the regular 6-point hex system. Ships may now turn 30 degrees to point toward a hex corner instead of just hex sides. Additional rules are included to address topics impacted by this modification in the movement system, including Collisions, Line of Sight, Firing Arcs & Range, Rakes, Marine Fire, Drifting, Anchoring, and Land terrain effects.
Additional rules include Impulse movement, Smoke effects, and Optional rules for Towing, Anchoring, Tacking, and Signaling. There are also optional rules for Pre-1794 Signaling limitations and a Signal Book for Pre-1794 scenarios.
