Stronger than Capped Ram. Slow, lumbering siege weapon used to reduce enemy towns to ruins.
Age of Empires II description

The Siege Ram is a non-ranged siege unit in Age of Empires II that can be trained at the Siege Workshop once the Imperial Age is reached. The wet hides of the Capped Ram have been replaced by metal roof armor for increased durability and strength. It is not only stronger than the Capped Ram, but also slightly faster, has an increased splash damage radius, and can garrison up to six foot units (infantry, archers, or Villagers), but only infantry units improve the speed and attack against buildings. Also, Siege Rams perform outstandingly against Trebuchets.

The * indicates that the civilization can fully upgrade their Siege Rams, i.e. gets Siege Engineers. Faith and Heresy are not taken into account because they only contribute to their combat strength in a very situational manner.

The ^ indicates that the civilization has at least one civilization or team bonus or a unique technology that benefits the combat strength of the Siege Ram.


Rams do not have any melee armor (in fact melee attackers get an attack bonus of +3), so any unit with a melee attack can destroy a Siege Ram rather quickly. The best ways to destroy them are with Mangonels, Mangudai, cavalry, or infantry. However, due to their high pierce armor and HP, they can withstand most ranged attacks easily. In fact, it is sometimes useful to add a few Siege Rams to an army for the sole purpose of soaking up enemy archer fire to protect the main force.

Siege Rams can cause enormous damage if left ignored. Although they can attack units, the damage they do is negligible. However, they can be used against Trebuchets and other siege units to good effect. The Siege Ram is good against arrow-shooting Towers, buildings, and Castles. In The Age of Kings, it is not recommended to use Siege Rams against Bombard Towers, because they deal melee damage. However, that was changed in patch 1.0b of The Conquerors, and Bombard Towers now deal pierce damage, meaning they do almost no damage to Rams.

Since The Conquerors, infantry and foot archers can load themselves into Siege Rams, increasing their speed and damage, and giving enemies a nasty surprise should they attempt to destroy it. The presence of units garrisoned inside a Ram is denoted by a flag on top of the Ram (similar to Transport Ships). A Siege Ram may load up to six units. The relationship shared between foot troops and Rams is mutually beneficial. When they are fully loaded, it is granted a speed greater than that of most foot units. Thus, the Ram may be used as a viable form of rapid transportation for the infantry and foot archers, in addition to providing cover from withering archer fire from Castles and Towers while the Ram closes the gap. Siege Rams can knock holes in Walls and then disgorge infantry directly into the enemy base.

Since The Forgotten, Villagers can also load themselves into Siege Rams enabling them to perform a distraction through deception by loading single Villagers in Rams making them effective dummies that can drive enemy forces away from the player's intended target, and enabling to perform offensive maneuvers. This new ability also enables to the Villagers to make them a better frontal support builders as they can travel inside Rams along with infantry and foot archers, and once they reach the intended place they can start to build frontal military structures.

Like with buildings, if a Ram is converted, units inside the Ram will not be converted. They will just be forced to leave the converted Ram.

Rams also provide protection to allied units behind them from arrow-fire of enemy fortifications (but not from projectiles of enemy units or ships). As long as the projectiles from the enemy defenses hit the collision box of the ram, the ram absorbs all the damage and the units behind remain safe. If a ram and a protected unit are close to the enemy's Castle or tower, the arrows fire from a greater angle, and some of the arrows can still hit the unit behind. Exceptions to this case include Villagers behind the ram. Therefore, a ram attacking a Castle even with Murder Holes can be safely repaired by a Villager for longer service.

This cover from arrow-fire is also provided by Siege Towers, and due to their larger size, Siege Towers can provide better cover to several units behind them, but they have a tendency to move away when under attack as their stance can not be set.

  • With the Mongol unique technology Drill researched, a Mongol Siege Ram fully garrisoned with infantry units has a speed of 1.2, the same speed as a Dark Age Scout Cavalry, and thus can move faster than most foot soldiers. Such speed and high anti-building bonus will allow Mongol players to quickly devastate a defensive fortification far more swiftly than conventional Trebuchet or Bombard Cannon tactics.
  • With the Celtic unique technology Furor Celtica researched, the Celtic Siege Ram has the second most hitpoints (378 HP) among all units in the game, only behind the Persian War Elephant.
  • With -3, the Rams have the lowest melee armor of all units.


The ultimate battering ram was the siege ram. This was a large engine that was heavily protected and designed to hit with a powerful force. Siege rams were often prefabricated weapons that were hauled to the site of the siege and assembled on the spot.
