I was thinking there could be more dynamic civillians in towns so if you walked into a village there could be a farmer with a stall or someone going on a jog through the town Or if your Going in a town thats just been attacked or had a battle go through it there could be a help point with lines of people cueing to gain supplies or in a battle in a town you could run through the empty streets into a house for cover and see a family cowering in a corner or someone shouting you too get out i think it would give a better urban feel
