A weapon or ability with this special rule can only be used once during the course of a battle. Once a weapon with the One Use or One Shot special rule has been used to attack, it is no longer counted as a weapon and may not be destroyed (for example, by rolls on the Vehicle Damage table) or repaired by any other rule or effect.
