[Beta 4][Suggestion] Militia defenses
It feels odd that a large city can be conquered by a single peasant if you are careless. Why would a city of 200 surrender to a lone peasant with a club? What about just converting a small percentage of your people to militia when you are attacked? They would just be a handful of crappy units but if you have city walls or the attacking force is very weak they could still win. Just base the number of these units off city size (or population). Maybe one per city size. The troops would be even worse then peasants so maybe give them 3 or 4 hitpoints and and attack of 1 with no armor. It would just offer a little realism and make cities a little more formidable.
