Focused Fire

Use this Stratagem after a T'AU SEPT unit from
your army inflicts an unsaved wound on an
enemy unit in the Shooting phase. You can add
1 to wound rolls for any other T'AU SEPT units
from your army that target the same enemy unit
this phase.
T'au Sept doctrine heavily emphasizes the massed concentration of fire upon a single target at a time, obliterating each component of the enemy force in succession with a series of unrelenting barrages.
