Crushing Assault

Use this Strategem in your Charge phase when a unit of Thunderwolf Cavalry in your army finishes a charge move. For each model in the unit select an enemy unit w/i 1" and roll a D6; on a 2+ that unit suffers 1 mortal wound.
With physiques more akin to Terran rhinoceroids than Terran canines, a Thunderwolf charge is deadly indeed.
