The Rohirrim Archers are equipped with bows and are skilled marksmen. They can shoot with deadly aim from their horses and can even shoot behind their backs, having the advantages and disadvantages of both Cavalry and Archers. They can also trample units, though they cause much less damage and suffer much more trample revenge damage than the regular Rohirrim or the Rohirrim of the Eastfold.
Reliable Aim - Even when firing from the backs of their horses, the Rohirrim Archers are able to detect and hit the weak points of their enemies. Their arrows can pierce heavy armor. (Passive ability)
Rohirrim Archers have access to the following upgrades:
Banner Carrier - This upgrade can only be given to a level 1 battalion and will promote it to level 2. At level 2 the battalion can regenerate units when out of combat. Cost: 200
Heavy Armor - Increases the armor, hit points and damage resistance of the unit to ranged damage. Changes the unit's armor set to EdainCavalryArcherHeavyArmor. Cost: 300
Although Rohirrim Archers have lost some of their power in recent patches, they can still be useful units. With their bonus against heavy armor and their good attack strength they can deal decent damage against most units with or without heavy armor. This makes them a strong fighting force, but be aware that they are vulnerable to enemy archers. Their speed allows them to both withdraw from battle if needed or rush to help friendly units in peril.
If you have trouble with your Rohirrim Archers running into the enemy, use the hold commad (hotkey:S) and put them on aggressive stance.
