When Torque arrives at this routine, he has determined that an enemy is on the same axis as him, and is either in front or behind. Therefore, it is possible that he can launch a missile at the enemy if it is in front of him, and if there are no barriers in the way.

If Torque finds that the enemy is in front of him, then he jumps to a routine to do a long range scan and find out whether the enemy can be seen or not.

Otherwise, the enemy is behind Torque and so it probably has a good chance of being able to launch a missile before Torque is able to turn round. In this case, Torque jumps to a routine to move out of the enemy's line of fire.
