sentences:  The missile is connected by a fiber-optical wire that is spooled out between the launch position and the missile.With this, the operator can obtain a target if it is not in the line of sight of the operator at launch, switch targets in flight, or compensate for the movement of the target if the missile is not tracking the target for some reason.Hence, the missile can be fired speculatively for a target of opportunity, or to provide observation on the other side of an obstacle.
