Medusa

Models with the Explorator Adaptation special rule gain a 6+ Invulnerable Save against Hits scored by a weapon with the Barrage or Blast trait.

Detachments with the Chain of Command special rule can only be issued an Advance Order unless instructed otherwise. If an Independent Unit contains only models without this rule, then that Independent Unit can be issued another Order, even if the larger Detachment can only be issued with the Advance Order.
