A model with this special rule is allowed to use non-Artillery Shooting Weapons against an enemy unit which is Engaged in Combat with friendly units if all friendly units Engaged in the Combat are Infantry and/or Swarms. All units Engaged in this Combat are ignored for Cover purposes. When shooting at an enemy unit Engaged in Combat with friendly units, roll to hit as normal and then randomize each hit scored. On a 4+ it hits the target, otherwise it hits a friendly unit Engaged in that Combat (randomize if several friendly units are involved in the Combat).
