Mod needed: +1 City Milita

I looked around using findstr on the XML files, and could not easily find an answer. However, I'm not really sure that adding a single militia unit will do very much for you. If you really want to change the defensive balance of the game toward cities, it might be best to override the various militia unit types and increase their strength.

You can increase the numbers of militia units in the coreimprovement.xml, in the improvements folder. They are added in the cityhub_X improvements, which is the city tile. However, militia are extremely weak, and you would get a lot more value if you made the militia stronger, or made them scale with your tech, like the militia armor mod does.

The AI is also weak in the late game.
