Shieldwall [Active]

(Rule)
Description: If this model is carrying a shield, then whilst it is in base contact with two or more other friendly models who also have this special rule and are carrying a shield, then this model receives an additional +1 bonus to its Defence. In Combat, this bonus is calculated before the model Backs Away. Models that are Prone or have the Cavalry keyword cannot benefit from, or provide an ally with the benefit from this special rule.
