If a squad of 9-Flamers of Tzeentch deepstrikes from reserves and tries to use breath of chaos to the enemy that is in its range, my question is that can the flamers use the breath of chaos? Because when they come from reserve with deepstrike formation(one flamer in the center, 5-6 in the first circle, 2-3 in the outer circle), some templates will cover some of its unit. So, in this case, the all flamers in the unit cannot use breath of chaos at all? Or only those that don’t touch friendly unit can be used?
