A for fun project!

Assume you are designing field armies (general purpose land combat) to combat opponents in more-or-less conventional warfare.

Each army may have a total combat troop strength of 100,000 persons.

You may combine troops of any nation or sub-era within the larger frameworks listed, but may not equip them with equipment better/substantially different then their own sub-era.

The eras in question:

Muscle-powered: 3500 BCE through 1350 CE

Gunpowder Era:1350 through 1850 CE

Early Modern: 1851 though 1960 CE

Later Modern: 1961 CE through Present


Delineate your forces and the reason for that composition.
