Command Protocols - Protocol of the Eternal Guardian

(Rule)
Description: Directive 1: Each time an attack is made against this unit, if it did not make a Normal Move, Advance or Fall Back this battle round, this unit receives the benefit of Light cover, as described in the Warhammer 40,000 Core Book. Directive 2: Each time an enemy unit declares a charge against this unit, if this unit is not within Engagement Range of any enemy units, it can either Hold Steady or Set to Defend. -If it Holds Steady, then until the end of the phase, any Overwatch attacks made by models in that unit score hits on unmodified rolls of 5+ instead of 6. -If it Sets to Defend, then until the end of the phase, it cannot fire Overwatch, but until the end of the next Fight phase, each time a model in that unit makes a melee attack, add 1 to that attack's hit roll.
