Laurels of Command wrote:Officer with Voice of Command ability only. Roll a dice each time the bearer issues an order to a friendly <Regiment> Infantry unit within 6" of them. On a 4+ the bearer can immediately issue another order to the same unit. This does not count towards the maximum number of orders this model may issue each turn.
Going by the rules above, the
Officer issues the first command to multiple units. Each time the Officer issues an order to a unit within 6" of itself, it may roll a dice and give an additional order to that unit if it rolls a 4+.
Thus, each unit issued the first order that is within 6" of the
Officer with Laurels of Command will have a
d6 rolled for it. On a 4+ that unit will have a second order issued to it. If those orders are from the list of orders that can be issued to multiple units, it can be issued to additional units within 6" of the target unit that have no already received an order this turn.
A unit can only receive a second order if it is within 6" of the
Officer with Laurels of Command and the dice roll for that specific unit is successful (aka 4+). Just being within 6" of a unit that received 2 orders via Laurels of Command is not enough.
