Land Raider Excelsior

While within 24" of one or more Rhino Primaris, add 1 to BS.

At the start of the shooting phase, choose a unit within 12" with the same faction as the Excelsior. This unit gains one of the following USR until the start of your next turn:  Counter-Attack, Fearless, Hit & Run, Interceptor, Preferred Enemy, Sky Fire, Split Fire or Tank Hunter.

Passengers disembarking from Access Points on a vehicle with this special rule can charge on the turn they do so (even in a turn that the vehicle was destroyed, or in the following turn) unless the vehicle arrived from Reserve that turn.

In a turn in which the vehicle neither moves Flat Out nor uses smoke launchers, the vehicle can fire one more weapon at its full Ballistic Skill than normally permitted. In addition, this weapon can be fired at a different target unit to any other weapons, subject to the normal rules for shooting.

If a shooting weapon has the twin-linked special rule, or is described in a model's wargear entry as twin-linked, it re-rolls all failed To Hit rolls.

For a Blast weapon, if the scatter dice does not roll a hit, you can choose to re-roll the dice with a Twin-linked Blast weapon. If you choose to do so, you must re-roll both the 2D6 and the scatter dice. 

Twin-linked Template weapons are fired just like a single weapon, but must re-roll failed To Wound rolls and armour penetration rolls.
