Civilization – How do terrain-based unit promotions work

civilization-5

If I promote a unit so that it is better a fighting of rough terrain for example.

When I am in combat and attacking an enemy, who needs to be in the rough terrain them or me for me to receive the bonus?

In general, it is determined by the tile on which the attacked unit is standing.

So, in case of melee units, it's where the combat takes place - i.e. in the hex containing the defending unit.

In case of ranged units, attack bonuses depend on the hex on which the target is standing.
