It is a crude heuristic that decides what to disband. Governed a lot by type. XP and level are included as well, but as an addition instead of a multiplier like with the type.Question for those that know about "STRIKES" Why is it that when a civ goes on strike, it always starts by taking OUT the Rogues and such? They are my best unit, besides the Hunter and Great General.
I'd suggest deciding yourself what to disband so you don't get into the situation when that code decides for you.
