I would just say that Polish forces saw action in WW2 actually much longer than many others. Yes, Poland was occupied in 1939 but their forces fought as part of the allied armies throughout the war and I believe in all 3 branches. Lest we forget the 1st Para brigade under Major General Gene Hackman (um maybe Stanislaw Sosabowski) during the Market Garden operation. I don't know if they require different counters since they were allied armed and I can't say that I know much about their organization (if different from the larger commands they served in). I think there was service on the Eastern Front too but I cannot say with any authority there.
