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 in an orbital barrage. If it does, select one point on the battlefield and roll one 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+ the unit being rolled for suffers D3 mortal wounds.
