Imperial Guard

Units with thisl rule count as having one more rank than normal for the purpose of combat resolution, up to a maximum of +4. Note that you still need to have at least one complete rank of 5 or more models for this rule to have any affect.

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.
