Wyverns

If this model is reduced to 0 wounds, roll a D6 before removing it from the battlefield and before any embarked models disembark. On a 6 it explodes, and each unit within 6" suffers D3 mortal wounds.

The first time this unit is set up, all models in this unit must be placed within 6" of each other. From that point onwards, each operates independently and is treated as a separate unit for all rules purposes.

Once per game, instead of shooting any weapons in the Shooting phase, the vehicle can use its Smoke Launchers; until your next Shooting phase your opponent must subtract 1 from all hit rolls for ranged weapons that target this vehicle.
