The first pictures show the masters mounted on a base board, which will then have styrene walls glued around the edges, so RTV rubber mold material can be poured in and cured. The masters can be made from plaster cast into a wood form, which is how original ones were made. This results in joints and wood grain being revealed in the masters.
The RTV rubber molds look like this. Curing takes 24 hours.
Concrete cast replicas look like this. We add nails to the bottom of each casting, so they will anchor into the ground and be immovable when struck by a model tank. A dime is shown in the pictures for persective.
We also use Mine Field Flags for a similar purpose, which are set around the battlefield by the defending team for each game. The metal rods are about 6” long and the flag is about 1.5” on each side. Should any tank run over one of these flags, and this is seen by an opposing tanker (and declared immediately), then the violator is out of the game. If such act is not seen then the violator may continue to play.
