Battering Ram

Battering Rams are slow moving siege units with an incredible attack bonus against enemy buildings and an incredible amount of ranged armor. The rams do not have any melee armor, so any unit with a melee attack can destroy a Battering Ram quickly. These can cause enormous damage if ignored. The best way to destroy them is with Mangonels.

In the expansion pack of Age of Empires 2 infantry can hide themselves in a battering ram.
