We added some extra green X's to mark blocked supply on rail hexes, and some iron cross and red stars to show where the closest supply points are. We think the original game was short a few.
These replacement game pieces are printed at 600dpi, laminated plastic, that are cut completely through for easy removal. They still require a sharp hobby knife and a pair of scisors because the lamination will stretch. Snapping forward and backward on a single game piece from a strip works well also. These are water proof, and very durable. They are thicker and heavier than usual (.067in) and are easy to pick up once you get the knack of handling them, and they stack better.
