Some units have ‘Scouts x"’ listed in their abilities. If every model in a unit has this ability, then at the start of the first battle round, before the first turn begins, it can make a Normal move of up to x", with the exception that, while making that move, the distance moved by each model in that unit can be greater than that model's Move characteristic, as long as it is not greater than x". 

DEDICATED TRANSPORT models can make use of any Scouts x" ability listed in their abilities, or a Scouts x" ability that a unit that starts the battle embarked within that DEDICATED TRANSPORT  model has (provided only models with this ability are embarked within that Dedicated Transport model), regardless of how that embarked unit gained this ability (e.g. listed in their abilities, conferred by an Enhancement or by an attached Character, etc.). 

A unit that moves using this ability must end that move more than 9" horizontally away from all enemy models. If both players have units that can do this, the player who is taking the first turn moves their units first.

Oath of Moment

If your Army Faction is Adeptus Astartes, at the start of your Command phase, select one unit from your opponent’s army. Until the start of your next Command phase, that enemy unit is your Oath of Moment target. Each time a model with this ability makes an attack that targets your Oath of Moment target:
■ You can reroll the Hit roll
■ If you are using a Codex: Space Marines Detachment and your army does not include one or more units with the Black Templars, Blood Angels, Dark Angels, Deathwatch or Space Wolves keywords, add 1 to the Wound roll as well.

Abilities
Morkai’s Howl: In your Shooting phase, you can select one enemy unit within 12" of this unit (if a LIEUTENANT IN REIVER ARMOUR is leading this unit, you can select one enemy unit within 18" instead). That unit must take a Battle-shock test, subtracting 1 from the result if it is a PSYKER unit. If that test is failed, in addition to being Battle-shocked, that unit is Stunned until the start of your next Shooting phase. While a unit is Stunned, each time a model in that unit makes a Psychic Attack, subtract 1 from the Hit roll.
Invulnerable Save: Models in this unit have a 6+ invulnerable save. This invulnerable save is improved to 4+ against Psychic Attacks.
Attached Unit: If a CHARACTER unit from your army with the Leader ability can be attached to a REIVER SQUAD, it can instead be attached to this unit.
