Unflinching Coordination

You can use this Ossiarch command ability in the combat phase after a friendly OSSIARCH BONEREAPERS HERO has fought for the first
time in that phase. The unit that issues the
command must be a friendly OSSIARCH BONEREAPERS HERO that has already fought
in that phase. The unit that receives the command
must be a friendly OSSIARCH BONEREAPERS
unit that is not a HERO, that has not yet fought in
that phase, and that is within 3" of an enemy unit. That unit can fight immediately.
