I would like it if civilians could kill one of your garrison when you take over a city. Say you have 5 Mech Infantry in a city with 10 people rebelling it would be good if there was a 10% chance that a unit of yours could be killed. How about countries being able to create terrorists of fund terorists so that they could attack an enemy by destroying a mine or killing some civilians. Or terrorists could attack one of your units without warning. I'd like to see more terrorism especially in the modern age with dirty bombs. It could be an idea for a terrorist to attack with a message appearing explaining the reason why the terrorist attacked- greater democracy, stop the war against China, lower taxes, give London back to the British we don't wanna be ruled by foreigners etc...
