How to use elephants?

[teja]

Eles are fast, they can move along with any cavalry based army and strike terror into all enemies. This are their main use. If encountering archers, try your best to push them back so they cannot harm you with flame arrows. When striking the enemy with your cavalry, keep your eles in 2nd rank to strike terror and are safe until the time is right to engage. In some kind it is similar to wardogs, which I seldom use until the enemy is routing. I take them with me just to strike fear in the enemies hearts. Unlike the dogs an elephant can do very much damage to almost any unit. Try to keep their fatigue low, because they go bersek more easy when exhausted.

As for the Macedonians I lack this kind of 'fear striking units' very much! In BI the Sassanids have such an awesome cavalry that the need for elephants is much lower but in vanilla RTW.
