Ancient armies fought at night or in foggy weather. Can they see clearly when they ride horses and shoot arrows?

I can't see clearly. But as long as you know where the enemy's phalanx is, you can shoot in the general direction. Anyway, the hit rate is similar. But because the line of sight is blocked. Therefore, under normal circumstances, few ancient armies are willing to fight at night or in bad weather, especially in wet weather such as heavy rain and fog, which will have a bad influence on the strings of crossbows.
