Perhaps due to their large size, their weight, or a combination of skittish draft animals and slow turning wheels, models with this rule are not especially manoeuvrable. To represent this, a Lumbering model is considered to be, and follows all of the rules for, a Close Order formation, even when included in your army as a single model.

However, even the largest single model enjoys slightly more manoeuvrability than a tightly formed regiment of many models. Therefore, after moving, unless it charged, marched or fled, a Lumbering model may pivot about its centre to change its facing by up to 90°.

Finally, a Lumbering model cannot join a unit or be joined by a character.
