Apart from Champions, who always fight as part of their regiment as described above, characters can move and fight on their own. In effect, they are individual units of one model. During the battle a character can join a unit of ordinary troops, in which case he becomes part of that unit until he leaves it.

To join a unit of troops a character has only to move so that he is touching it. Once he has joined the unit the model is automatically placed in its front rank. Note that a character will inevitably use up a proportion of his move to reach the unit he is joining. If the unit has not already moved then its further movement is limited to that remaining to the character; any movement lost represents time wasted waiting for the character.

Although characters are normally placed in the front rank of a unit they join, if the unit is already engaged in combat then the character may be placed anywhere in order to fight an enemy - even at the sides or rear of the formation. However, once combat is over the character is automatically placed in his rightful place in the front rank.
