Siege unit

Siege Weapons are units created at the Siege Workshop and are machines created for to fill different roles in battle. They generally feature high damage, slow speed, expense, and vulnerability.

In Age of Empires II
Siege weapons are best divided into two categories: units that are anti-building, and feature high siege damage against buildings, and units that specialize in splash damage.

Anti-building units include:


 * Rams
 * Bombard Cannons
 * Trebuchets

Splash damage units include:


 * Scorpions
 * Mangonels and their upgrades.

Although the two types of units can still fulfill each other's roles, they are generally extremely ineffective at doing so. For example, while mangonels are devastating against groups of infantry, they barely deal any damage to castles; trebuchets, on the other hand, are excellent against castles but almost never hit the units they target.

Sometimes the two groups can overlap in their purposes. Trebuchets and Siege Onagers are both adept at clearing trees, for example.
