A model with this special rule is allowed to use non-template shooting weapons against an enemy unit in close combat with friendly units, of infantry, warbeasts or swarms, not containing any characters. When firing at an enemy unit in close combat with friendly units, roll to hit as normal and then randomize each hit scored. On a 4+ direct it against the target. On 1-3 direct it against a friendly unit in that combat (randomize if several friendly units are involved in the combat).
