Inaccuracy An Orbital Strike scatters just like ordinary ordnance weapons, except when a miss is rolled the distance scatterd is double the number scored on the D6. If a hit is rolled, the template deviates by the distance shown on the Hit Symbol.
Timing An orbital strike uses the Reserve special rule to determine when it strikes. Once the orbital strike passes the Reserve roll it fires each Space Marine shooting phases for the rest of the game. It cannot be stopped once started. The Space Marine player can opt to not roll for the onset of the orbital strike if they wish.
