Tactics
Onagers are best used with other units, such as knights or elite infantry for protection. Since they move very slowly, this expensive unit should be protected at all costs. An Onager works best behind the battle field in conjunction with a large group Archers. One way to use them to attack Archers and other Onagers is to send them one by one. Then, although they will be destroyed, the enemy is likely to lose 3 units, or even 10 if the other player puts them in line or flank formation.

Onagers, Mangonels, and other siege units are very effective against naval units, and once Heated Shot is researched, they have the potential to destroy even Turtle Ships in a few shots. The AI will often send out onagers as a shore defense to protect its buildings against Cannon Galleons.
