These replacement game pieces are printed at 600dpi, single sided, 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 streach. 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.
For the variant counters we added heaver and lighter units for the various major countries - there was no way the USA deserved all 5-6 armor units when they had Stuart and Lee tanks to start with and the Sherman just wasn't up to taking on Tigers or Panthers one on one. You can negotiate the counter mix before play, and also replace weaker units with stronger ones on a specific date if you want. Lots of options now.
