I do not play Squad Leader because it is far too complex for my taste, but I do use the geomorphic game boards for my home-grown games.
The photo shows a Napoleonic battle in progress. Each infantry block represents a close order company of 60 men in two ranks or 90 men in three ranks. “Dotted” infantry are skirmishers, representing 30 light infantry. A French light Infantry battalion can be seen advancing through the woods on their right flank in skirmish order.
For cavalry a block represents three ranks of 10 men and artillery blocks each represent a gun and crew.
For these games I halve the Squad Leader claimed ground scale so that each hexagon is 20 yards across (could also be 20 paces or 20 metres according to period).
The plastic blocks are sourced from “Plastics for Games” with labels created in Excel.
I aim to eventually own the entire collection of ASL boards. My stock of boards is currently:
1,1,1,2,2,2,3,3,4,4,4,5,5,6,6,6,7,7,7,7,8,8,11,12,12,12,13,14,15,17,21,22,23,24,25,26,29,39,40,41.
When I set up a game I take the stack of boards and roll three dice to select which three boards from the stack I will use. A further die roll decides the orientation of each board.
As I go through the stack to select the boards for play, boards that are not chosen go to the bottom of the pile, thus further randomising future selections.
