Troops blocks
These troops are the easiest to make but cost a little more since you need to buy cubes.
You will need those cubes for your concealed troops and dummies.
Cubes of 1cm size are probably the best compromize between costs, handling and visibility.
The dummies are just the coloured cubes which you can get from stores or internet shops. You can both use wooden or plastic cubes, but make sure that they all look the same.
For the concealed troops you use those same cubes but mark them on one side with printed adhesive icons, which you can find in the download section.
