Reaver

Can ignore terrain when moving but must roll a D6 when moving in or out of Difficult Terrain. On a 1, the model is killed with no Armor Save allowed.

Treated in the same manner as a normal jetbike, apart from an added turbo-booster. This may be activated in any movement phase, and increases the jetbike's move to 24". However, the model may not shot or assault on the same turn the booster is used. When a Reaver uses its jetbike's turbo-booster then its saving throw becomes invulnerable for that turn and the opposing player's following turn. If one model in a unit uses its booster than so must all the others. Characters riding a Reaver jetbike may only be armed with single-hand weapons and may only use one at  a time.
