Hello I found it bit inaccurate to see Many Polish last names in that both campains while they clearly they do not belong in battle of moscow or battle of berlin, as moust of recruits from Poland where moustly delegated to France as they where highly propable to start mutinies what could cause big problems in their local region (as they where enlisted by force in some regions of poland like Silesia, and volounteers to wermaht where very rare as moust of the willing to fight folk where in polish underground army). And it is quite difficult to argue that they are gemans as it is incredibly common for polish emigrants to change their names to suit pronaunciation of the region ( for example : Trzmiel-> Tramel ( US), Skorzęcin → Skorzeny (Germany)).
I know it’s alpha but i would be willing to take my time and flag list of directly polish names as this is very immersion crushing for me and i have roughly a week of free time (another thing is that my own Great-garndfather was forcefully enlisted and died on the D-DAY).
