The rules were home-grown, developed by Ron, our host -- referred to as "Red, White, Blue, Green, Yellow, Black."
They use correspondingly-colored D6, D8, D10, D12, D16, and D20 dice to determine casualties. Roll a 1, inflict a casualty; Roll a 2 or 3, suppress an enemy figure for one turn.
The distance from your target determines which die to use -- close range uses a D6, longest range uses D20.
