So the reenactment group I am a member off portrays Hussite mercenaries. This is a groups from what is now the Czech Republic in the 1420s, who were basically badass peasants who rebelled against the Catholic Church with such radical ideas as *a bad priest is no priest at all* and so on.

They are famed for using mobile "battle wagons" in their warfare, and a friend's small one wanted a toy wagon to play with on camp. So I made one for Xmas!

The chalice on the flag is because the movement believed that everyone, peasants included should be allowed "communion in both kinds" as at the time only the rich got wine at mass, and so were somehow more "blessed"..... Anyways.
