"Models with this Special Rule can make Volley Attacks with other Weapons."

"A Model with this Special Rule can explode and cause Hits to nearby Models and Units."
Before a Model with the Explodes (X) Special Rule is Removed as a Casualty, the Controlling Player must roll a Dice. If the result of that roll equals or exceeds the value of X attached to this variant of the Explodes (X) Special Rule, the Model explodes. Every Unit with one or more models within 6" of an exploding Model suffers a number of Hits equal to the Base Wounds Characteristic of Base Hull Points Characteristic of the exploding Model.
