How many unit types will each civilisation have available?
The maximum possible unit set available to a civilisation is 5 military foot units (Infantry Citizen Soldiers), 4 military cavalry units (Cavalry Citizen Soldiers), 3 support units, 3 siege weapons, 4 ships, 2 Super Units, and 3 Heroes. No civilisation gets all categories, and some lack as many as 5 different unit types.
