Hydra Platform

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 3" suffers 1 mortal wound.

The first time this unit is set up on the battlefield, each model must be placed within 6" of each other. After this unit has been set up, each model is treated as a separate unit. If this model contains any crew, they are ignored for all rules purposes.
