Warriors in the second rank may make supporting attacks.
A model can make a supporting attack if it is in the second rank and directly behind a friendly model that is itself fighting an enemy in base contact. Supporting attacks cannot be made to the side or rear or by models that are in base contact with enemies.
The number of supporting attacks each model can make is dependent on their troop type, as explained in in the troop types chapter.
Supporting attacks are made against models in base contact with the front rank model that is being fought 'through'. If the front rank model is in base contact with two or more enemies with different profiles, the attacking player can only direct the supporting attacks against normal rank and file models in the unit. This means they cannot target specific models like characters, handlers or other unique models, unless those are the only options available.
