A unit with this special rule reduces the number of wounds suffered due to the Unstable special rule by the number shown in brackets (shown here as 'X').

Note that this special rule is not cumulative. If two or more models in a unit have this special rule, use the highest value for the entire unit. For example, if a character with Indomitable (2) joins a unit with Indomitable (1), the whole unit uses the character's Indomitable (2) special rule.
