Concussive (X) A unit that suffers one or more Wounds, regardless of whether those Wounds are Saved or otherwise discounted, from a weapon with this special rule must take a Leadership test at the end of the Shooting phase (if the attacks were inflicted as part of a Shooting Attack), or the current combat (if the attacks were inflicted as part of a Melee attack). If the test is failed then that unit’s WS is reduced by the value in brackets listed as part of the special rule until the end of the following Assault phase (if no value is listed then reduce the target unit’s WS by -1).
No matter how many times a unit has taken saved or unsaved Wounds from an attack with the Concussive special rule, it may only be forced to take one Leadership test because of it. If a single unit has been the target of several Concussive attacks with different values and fails the Leadership test, then it suffers the effects of the highest single modifier among those attacks – the effects do not stack or otherwise become cumulative.
