The Iroquois really focused on their harvest, their domestic food plants, and their agricultural way of life and we've tried to reflect that in their in-game economy.

Well, each native nation actually has its own unique set of units. Returning from Age3 are the Iroquois Tomahawk and Mantlet units, although their stats have changed and now all Iroquois units will cost population slots. There are about 6 new military units including the Aenna, the classic foot-archer unit, and the Musket Rider which is a musket-carrying cavalry unit representing the European influence on the Iroquois. It's a bit early to talk about technologies since these can change often throughout production, but we hope to share more in the near future.
