It fires salvos of 5 shells each at intervals of 1 second per shot, with 3 seconds between salvos. The shells are 380mm HE Barrage shells that walk forward in the direction the beacon was thrown. The barrage advances around 100 meters from the start point.

Instructions: Add additional tips
  • The walking barrage allows players to follow the advance of the barrage, which travels in the direction the player faces when calling in the stratagem.
  • The stratagem beacon stays at the initial call-in location, therefore as the barrage continues it becomes more misleading about where the danger zone is.
