I don't know if this has been discussed before, so sorry in case.

Wenn you attack a city and the city has walls there's an animation played where a ranged unit defends against the attacker by shooting back. This happens regardless of an unit actually being in the city.
Which animation is played depends on the era. So in vanilla you see either Slingers/Archers (Ancient), Crossbowmen (Medieval), Field Canons (Rennaissance) or Machine Guns (Atomic) defending.

Unfortunatly in Anno Domini these animations are also used. For me that's quite an immersion breaker.

Is it modable at all?
