You can only have so much historical accuracy, if we push it to the max, like you seem to be focused on, then there is no point of having Saba or Sweboz . It was an example. How nice of you to dismiss it as trolling.

And Saka bringing 15 infantry units is highly unlikely. Even 10 is a gamble. If they do bring that many, you will have an instant advantage since Sakae infantry with the exception of the Indian Srenis are pathetic and only good at holding a line, not winning a battle.
