Orbital Comms Array

In your shooting phase, one model from your army with an Orbital Comms Array that has not been used this battle can use it to call an orbital barrage. If it does select a point on the battlefield and roll a D6 for each unit within D6" of that point, subtracting 1 from the result if the unit being rolled for is a CHARACTER. On a 4+ that unit suffers D3 mortal wounds.
