Scout Bike Squad

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.

During deployment, if every model in this unit has this ability, then you can set up this unit behind enemy lines instead of setting it up on the battlefield. If you do, then in the Reinforcements step of one of your Movement phases you can set up this unit wholly within 6" of any battlefield edge and more than 9" away from any enemy models
