Mount Effect?

[Mykingdomforanos]

Does anyone know this? I might have explained it wrong.

In the export_descr_unit.txt it says:

mount_effect
Factors to add when in combat against enemy units that have the specified mounts
Up to three factors may be specified, which may be classes of mount, or specific types

Wondering if "combat" refers only to melee ,or missile also?

I guess its meant to be melee only as for instance some archers have -2 to horse
