No screenshot as I do not know how to picture that in one. Sorry!
I enabled the Military Academy (and therefore Armies) to be build without existing Armies. And the KI loves them both.
And I have observed that KI-controlled Armies allways went pillaging through enemy land.
Today I discovered that they also pillage in neutral land.
The Iroquois had build under great difficulties a railroad over a mountainrange to one of their cities. A large part of that railroad lied in the uncleamed mountains.
And then they sent an Army to that city to be loaded into a ship.
The Army demolished the complete road and railroad on its trip!
