A unit that contains only models with this special rule ignores modifiers to Leadership when making a Morale check or Pinning test - except those caused by the Fear (X) special rule or the Corrupted and Anathema Sub-types. If a unit has both the Fearless and Inexorable special rules, it uses the rules for Fearless instead of Inexorable.
