Skirmishers move in a loose group or rough line. Models are positioned up to 2" apart so that they are not touching each other. Should the group be split as a result of casualties, or should individual models become divided from it for some reason, then the player must rectify this in his next movement phase.
Skirmishing models are moved as individuals in the same way as characters. Any model can be turned to face any direction as it moves and no penalty is incurred for this.
Skirmishers are uninhibited by their fellows and so have freedom to move around obstacles or rough ground. They therefore suffer no penalties for crossing obstacles or difficult ground.
