5-11 their pouches. If the practice aboard your ship is to carry the pistol loaded, NEVER have a round in the chamber. 4. When being relieved, always unload the pistol and inspect it for a clear chamber. With the pistol pointed in a safe direction, release the slide and snap the trigger. The use of a firearm comes under the term deadly force. Deadly force is that force which a person uses with the purpose of causing—or which they know, or should  know,  would  create  a  substantial  risk  of causing—death  or  serious  bodily  harm.  Its  use  is justified only under conditions of extreme necessity as a last resort, when all lesser means have failed or cannot reasonably be employed, and only under one or more of the following circumstances: Self-defense Defense of property involving national security Defense of property not involving national security but inherently dangerous to others, such as the theft of operable weapons or ammunition Prevention of the commission of a serious offense involving violence and threatening death or serious bodily harm Authorized detention, apprehension, and escape prevention of a person likely to cause death or serious bodily harm to another Direction by lawful order of a superior authority Details of the above circumstances can be found in OPNAVINST 3120.32. WATCH-TO-WATCH WEAPONS TURN- OVER.—Having stood your watch, it is now time to be relieved  as  POOW.  Besides  passing  along  all  the necessary information to your relief, you now have to turn over your weapon to your relief as well. In the quarterdeck area or nearby, you should find a logbook that is used to record passing of the custody of your weapon and the ammunition provided for it to your relief. Usually there are three magazines with your pistol. Two of the magazines, each containing five rounds, are in pouches attached to the pistol belt. The third magazine is empty and is in the pistol to protect internal parts of the pistol from the weather, dirt, and dust. Remember, a dirty weapon can jam when firing and cause serious injury to you. If the pistol has a lanyard attached to it, keep the lanyard around your neck until your relief has positive control of the pistol. Then remove the lanyard from around your neck and place it around the neck of your relief. This effort prevents the pistol from being dropped and damaged. Verify the serial number of the pistol with your relief. Also count the ammunition by looking at the side of the magazine where there are small openings to make sure that all the rounds are there. If there are five rounds in a magazine, you will see the brass casing of the bullet in the third opening from the bottom of the magazine. Drills and Emergencies In the Navy you have been taught that training pays off. The more you train, the better you perform. The same is true with drills. Drills are held for only one reason and that is to be prepared in a real situation. Proper damage control training has made the difference between winning and losing battles on several occasions. As a petty officer you will be assigned greater responsibility   within   the   damage   control   (DC) organization. You may be assigned duties as a division damage control petty officer (DCPO), which is covered in chapter 6, or in any other position in DC. You may be called on to assist in training assigned personnel. As a trainer, you must ensure that your trainees are capable and ready to respond should damage occur. All damage control personnel must know how to apply the correct principles and use the materials available in the most effective way possible. That knowledge can be gained only through education, training, and actual practice. Injury or incapacity of one individual should not significantly reduce the effectiveness of any damage control function. For example, repair party personnel must be “jacks-of-all-trades.” They should be able to do each other's jobs, and this can be done only by cross training  in  each  other's  skills.  In  an  emergency, widespread capability may be needed to save a ship.
