Exactly, mid level units. Arty in game makes all city defence mechanisms almost useless. It doesn,t matter whether a city a 150 or 20. It only takes several turns more to capture the city.
Maybe I am just bad at laying siege to cities but a city with 200 HP and 100 strength is not easy to take, especially if the terrain is not favorable. If you can't get at least 3-4 artillery units in range, you have little chance of taking the city in my experience.
