Torque goes to this routine if an emeny has appeared on his perimeter
and then disappeared again without leaving a flag. This can mean that the
enemy has backed away one space in preparation for launching a missile
at Torque. In order to deal with this situation, Torque moves out of the
line of fire, or if he is facing directly towards or away from the enemy
then he moves toward it so that it can't safely launch a missile without
being caught in the splash.
