This unit has the following abilities: And They Shall Know No Fear, Bolter Discipline, Shock Assault and Combat Doctrines.
Before any models are deployed at the start of the game, this unit when containing its maximum number of models, may be split into two units each containing an equal number of models.
Whilst the Assault Doctrine is active, if an unmodified hit roll of 6 is made for an attack made with a melee weapon by a unit with this ability, that attack scores 1 additional hit on the target.
