This Formation must be from the Salamanders Legion and can only be included in an Army with the Loyalist Allegiance. In addition, an Army can only include one Salamanders Saturnine Heavy Assault Cadre Formation.
When a Saturnine Terminator model from this Formation Disembarks from a Mastodon model from this Formation, weapons that Saturnine Terminator model has gain the Shred trait until the end of the round.
Any successful Save rolls made by an Infantry, Walker or Cavalry model using its Armour Save characteristic against a Hit scored by a weapon with the Shred trait must be re-rolled.
