We played a Cold War game this week. The Warsaw Pact, all Russians in this game, advance against a mixed force of NATO defenders (Belgians, Brits and West Germans).
All of us were old enough to remember when this was ultra modern. The miniatures are Heroics and Ros 6mm. I think many are of a similar vintage to us and if I'm right they have held up remarkably well for their age. Better than me anyway.
For rules we used A Fistful of Tows 3. These rules are platoon based, so a vehicle model represents 3-4 real vehicles. This allows a lot more of the the rear echelon kit to make it on to the table.
We used cm for measurement but this made ranges and movement very small and maybe inches would be better,
