Immune to Psycology Some warriors and creatures in the Warhammer world are almost completely fearless, or such grizzled veterans that scenes which would make lesser troops panic have no effect on them.
Troops that are immune to psychology are never affected by fear terror, frenzy or any other Psychology rules. Troops immune to Psychology may never flee as a charge reaction - they are far too proud and brave to do this! These troops still have to take Break tests as normal.
Bull charge If a unit of ogres moves 6" or more when charging, they can benefit from the Bull Charge. For every charging ogre in base contact with the enemy, one impact hit is inflicted on the charged unit. Additionally, if the charging ogre unit has multiple ranks, ogres behind those in base contact also inflict an impact hit on the enemy. For instance, if a nine strong unit of ogres with three ranks charges an enemy unit, a total of nine impact hits are inflicted (provided that all three ogres in the front rank are in base contact with the enemy unit.) The strength of the hit is identical to the ogre inflicting it.
