Should the text of Shock and Drill not be (I added the correct text in bold):
Drill:
+20% Combat Strength when fighting against a unit in ROUGH Terrain. (Hills, Forest or Jungle)
Shock:
+20% Combat Strength when fighting against a unit in OPEN Terrain. (NO Hills, Forest or Jungle)
Drill:
+20% Combat Strength when attacking a unit standing in ROUGH Terrain. (Hills, Forest or Jungle)
Shock:
+20% Combat Strength when attacking a unit standing in OPEN Terrain. (NO Hills, Forest or Jungle)
