Surprise Assault

Play this card at the start of the battle after deployment. Your opponents are so surprised and hurried, that they cannot set overwatch and may not make any run or charge moves in their first turn. Vehicles cannot accelerate on the first turn. In their second and subsequent turns the enemy army may act normally. If the enemy is allowed to start the battle in overwatch for any reason, such as the Ambush Strategy card or Tyranid Trap mission, the squads on overwatch must pass a Leadership test or lose it.
