So far all of the Andreivian games have been played in 20mm scale. This is of course the right and proper scale for skirmish games. Apparently other scales can also be used but only by freaks and perverts who are lower than a maggot in the eyes of real wargamers.
However, 6mm scale is acceptable for bigger, grand tactical games. And it's been suggested that next year's SOTCW participation game might be Cold War Commander in Andreivia. The constraint is that we want to use The Baggage Train's giant Arnhem Bridge model. For details of SOTCW games past see the SOTCW Events blog:
