While a character is with a unit of troops he is considered to be part of that unit in all respects. This means that if the unit flees then he must flee along with them at the same speed, if the unit pursues then he must pursue with them as well, if the unit declares a charge then he must charge as part of it. Some implications of this are discussed in the following paragraph.
If a unit of troops panics, or is forced to flee because of a failed, then any character who is part of the unit must also flee even if he is immune to , or terror. If the unit is affected by or forced to pursue because of , the character must move along with the unit but does not benefit from any bonus unless he is affected by frenzy/hatred himself. In other words, a character does not go into a frenzy just because he is with a unit that can do so, although he has no choice but to accompany them when they charge.
If a unit is affected by stupidity any characters must move as the unit moves, although the character can fight normally unless he is stupid himself. Remember, a character cannot leave a unit when it turns stupid and stands still or moves stupidly because such a unit is bound by a compulsory movement rule, the character muse therefore stay put. We can imagine he is trying to goad the stupid creatures into activity, or perhaps he is pinned down or hemmed in by the dribbling brutes and unable to move of his own volition.
If a character is liable to a Terror or Fear test which doesn't apply to the rest of the unit, he can ignore any tests. For example, if a character who is subject to fear is in a unit of fear-causing troops, such as Ogres, and is charged by enemies who cause fear, he does not have to take a Fear test.
