The Ironguts failed 1 save, which finishes off the wounded one, leaving me with 5. The Ironguts do 4 wounds, they can be parried. The Slaughtmaster & BSB do 2 wounds by stomping, which can't be parried, and at S5 should ignore armour. The Champ's stomp wounds too. It is S4, so though there is no parry, I think you get a 6+ armour save.
