SMASHING AND BASHING

In the combat phase, after a friendly IRONJAWZ
unit has fought, if the attacks made by that unit
resulted in any enemy units being destroyed, you
can pick 1 friendly IRONJAWZ unit that has not
yet fought in that combat phase and that is within
3" of an enemy unit. That unit fights
immediately, before the opposing player picks a
unit to fight in that combat phase. That unit
cannot fight again in that combat phase unless
an ability or spell allows it to fight more than
once.
