While a Detachment from this Formation contains a Tank Commander model, that Detachment has the Nimble and Steadfast special rules.
Models with the Nimble special rule suffer no penalties in their Movement when moving through areas of Difficult terrain.
A model with the Steadfast special rule counts its Tactical Strength as one higher than normal (e.g., an Infantry model with the Steadfast special rule would have a Tactical Strength of 6). This rule is cumulative with other special rules.
