Units/vehicles under a barrage's template squares become Pinned.
So if a unit/vehicle remains under an active barrage for two or more turns will the unit/vehicle become Suppressed, as per the rule that Pinned units/vehicles that receive a second Pin become Suppressed (the subsequent Pins coming from each additional turn of barrage), or is Pinned the worst that be applied to a unit/vehicle under the barrage's template squares regardless of the number of turns spent under the barrage, barring any other event that would inflict a Pinned result on said unit/vehicle?
