Figures are mounted 3 to a 40mm wide by 30mm deep base. This basing will be suitable for Fire n Fury or any number of other rules.
I've based 28mm figs individually before but this is the first time mounting multiple figures on a base, so I decided to spend some time with the bases. The bases are covered with "scenery mortar," a powder that is mixed with water and spread on the base and pushed up around the figure bases. The scenery mortar seems to be a powder mix of fine sawdust and glue that binds all together with the added water. Model railroader use this stuff a lot and for me it is easier to work with than spackle compound from the hardware store. Added some ballast and rocks to the wet mortar.
Anyway, after the mortar dries, about 8 hours, I brushed it with Earth Undercoat (Woodland Scenics product) mixed with water and white glue to add color to the mortar and some more binding to the ballast and rocks. When that dried I then added the tall grass and static grass followed by dry brushing of the base. Viola.
Next I'm doing the Yankees.
