If the majority of the models in a unit are Stubborn, the unit is always Steadfast, whether or not they have a higher Unit Strength than their enemy or are disrupted.

Models with this rule must always accept challenges and re-roll all failed Psychology tests. In addition, they treat friendly units without this rule as Expendable.

If the majority of models in the unit has this rule and are garrisoning a building or fighting behind a defended obstacle, they may re-roll failed Break tests.

Whenever a unit comprised wholly of models with this rule is required to take a Break Test, they may choose to do so using 3D6, discarding the highest dice. However, if this test is failed, you must remove the entire unit as a casualty. The enemy then cannot pursue or overrun, but may reform as normal.
