John Black's Mercenaries, though based in United States, possess the unique cavalry units of Germans, while their home city is based on the home city of the Dutch - Amsterdam. They do not get any special civilization features, such as extra Uhlans or requiring more experience per shipment.
Unlike the Germans, they have access to Musketeers, Halberdiers and Grenadiers
Their Skirmishers and Uhlans do not get the Royal Guard upgrades.
They use the British architectural style for their buildings, except for their House, which is similar to the Germans.
All of their units speak Old English (same as the British), except for their cavalry units, who speak the usual German.
