Onager

Template:UnitInfoBox

"Onager: These early catapults were based on ancient Roman technology, they used tensioned rope that when released launched stones at enemy fortifications."

"Catapult: Catapults were increasingly important as a weapon to destroy castle fortifications as castles became bigger and stronger."

"Mangonel: Mangonels were similar to trebuchets in that they used counter weights rather than tensioned rope to trigger the launch of projectiles."

Offensive Strategy

• Target a wall outside the range of a tower and one can take down one or two surrounding buildings or defense without taking any damage.
• Usually not used when compared to trebuchets but can be used, maybe one, at the end of the battle to inflict some strategic damage and earn 2 stars.
• Siege rush with Conrad the Elder is still good in Age VII: 2 trebuchets + 2 rams + 5 onagers + protecting units like mamluks

Defensive Strategy

• Onagers CAN NOT be used in defense.
