War Chest: Shock Tactics

From BoardGameGeek:

In the distance there is a faint rumble. Gradually, that rumble becomes growing thunder as thousands of mounted knights crash over the ridge. The very earth shakes as the sun glints off clamoring shields and armor. The points of long, wickedly-sharpened lances are aimed directly towards their foe, and the wild eyes and glistening flanks of mighty war horses charge forward. Who could resist such an onslaught? In War Chest: Shock Tactics, you will have the opportunity to use new units that affect the very morale of your opponent's troops. Whether it be the steady, daunting beat of War Drummers, the terrifying Greek fire raining down from Pitch Throwers, the will-sapping Raiders, or the reimagined units from the original game now returning as Heavy Cavalry, Vanguard, or Warlord. You will be changing the way your opponent thinks. It is time to employ Shock Tactics! -description from the publisher
