Description: Once per battle, during their turn,m the controlling player may declare that they will activate their Orbital Defences. Until the end of the opposiing player's next turn, any Reserve rolls that the opposiing player makes suffer a penalty of -1 and all rolls made by the opposing player to determine if any Deep Strike Assaults, Outflanking Assault or Subterranean Assaults are Disordered fail on the roll of 1-3 rather than just the result of a "1" (neither of these effects stack with other special rules that modify Reserves rolls of Disordered rolls, and the controlling player must choose one effect to apply). In addition, if the opposing player of a player whose army includes one of more models with the Orbital Defences special rule declares a Drop Pod Assault, the then controlling player of the models with the Orbital Defences special rule may roll a dice when the Drop Pod Assault is resolved. The controlling player of the models with the Orbital Defences special rule may select a number of enemy models with the Orbital Assault Vehicle special rule equal to the result of the dice roll, each of the models selected suffers a single Str 8 Ap 2 Hit after it is deplyed onto the battlefield.
