When an observer unit uses the Artillery Strike ability when the artillery unit has LOS to its target you are allowed to make a "Direct fire" shot instead of an "Indirect fire" shot, does this mean that you can either make a "sustained attack aka SHOOT+SHOOT" or a "SHOOT+MOVE" action with the artillery unit?
Quote from Operation Cyclone rulebook page 4: From "Indirect Fire"
"" The unit with the Artillery Strike ability is called an "observer." It is the observer that triggers the shot. So, the observer unit must have a clear line of sight to the target (if the artillery does have line of sight, it makes a direct shot instead). ""
