Main question
When a crossbowman or handcannoneer is stationed within a keep or landmark like “barbarican of the sun”. The attack of that unit is displayed as that of an archer.
Is this a bug? Or is there some good reason behind this particular notion?

Should this be changed?
Who thinks this is bad or good design?
