The Cavalry Archer is the most expensive Archery Range unit, so it is not used commonly. However, if you have plenty of gold at your disposal, Cavalry Archers are very strong when massed. They are quite fast and are strong against most units. Very useful in the early Castle Age for raiding the enemy's economy and later on for destroying the enemy trade. It is ideal to have units in front of your cavalry archers when using them on the main battlefield since replacements are costly to come by.
