Hussars). Contrary to legend, WW2 Polish cavalry didn't make any ridiculous attempts to charge tanks with this weapon (or sabers for that matter). Instead they had an extremely deadly anti-tank weapon. What you might ask? Considering the invasion of Poland took place in 1939, there was no such thing as the bazooka, panzerschreck or panzerfaust. Simply put they used special high powered rifles.
There are a number of smaller nods to the real history of Poland as well. The persecuted Darcsens are combination of Jewish people living in Eastern Europe and Polish workers forced to labor under harsh conditions in Axis factories. Obviously, the geographical location of Gallia on the map of Europa corresponds rather well to the location of Poland on an actual map of Europe. Then there's the term "Valkyria" which sounds like a derivation of "Valkyrie," women who according to Germanic folklore, were imbued with superhuman abilities.
