there used to be a militia mod, but I can no longer find it. i thought that it was great for BNW since the AIs do no build sufficient defensive units. any one know what happened to it?
It was one of FramedArchitect's mods if you are talking about this one:
Militia Defense v.4 Militia automatically rise up to defend against invasions. Mod Mechanics When an enemy unit first enters their civilization's territory, one Militia is raised near each city with a population of at least three.
