     c.  You will insure that you exert every effort to maintain constant proficiency in your ability to distinguish the differences between the sound and appearance of the different types of weapons available to the enemy so that you can report factual and expert infortion to CSC.

     d.  During hostilities you will not attempt to engage in a fire fight unless fire is being directed at you.  It is highly essential that your position is not observed by the enemy.  You are the single most important element of this installation's defense.  You will take only those actions necessary for the defense of yourself, your position, and your assigned equipment.  Unless specifically ordered or cleared to do so otherwise, you will not remove yourself from your tower during actual or imminent attacks of any nature on this installation or the surrounding area.

particularly in relationship to artillary assaults, must be nearly instantaneous reaction.  You will exert every effort to insure that to the extent possible you are scanning 360 degree from your position and never dwelling in a specific area until the action is clearly committed to that area.  On the multi-manned towers, only one operator will focus his attention to the specific action.
