Vicious Descent (The Murderflock) All units in a Murderflock begin the game in Strategic Reserve. When they become available, you may delpoy a single unit from the formation by Deep Strike without scattering. All other units in the formation must then deploy by Deep Strike without scattering, and within 6" of a model from the first unit deployed.
Once this is done, enemy units within 3" of any model from this formation suffer 2D6 Strength 4 AP5 hits with the Redning special rule (vehicles are hit on thier side armour). Keep track of unsaved wounds caused. Once this process is complete, every unit in the formation gains a pain token for every five unsaved Wounds (or part thereof) caused. For instance, if a Murderflock causes 11 unsaved Wounds with its Vicious Descent, all of the units in the Murderflock gain three pain tokens.
