Kampuchea Iran Libya Mongolia North Korea South Yemen (Peoples Democratic Republic of) Vietnam (Social Republic of) Dips by yachts displaying a yacht ensign are also returned. The yacht ensign is similar in design to the U.S. ensign except that the blue field contains a white fouled anchor surrounded by 13 white stars. Submarines, or such other ships of the line in which it would be considered hazardous for personnel to do so, are not required to dip the ensign. Of the colors carried by a naval force on shore, only the U.S. Navy flag and the Battalion Colors are dipped in rendering or acknowledging a salute. UNION JACK The union jack, when displayed from the jackstaff, is the same size as the union of the ensign displayed from the flagstaff. When a naval ship is not under way, the union jack is flown from the jackstaff from 0800 to sunset. It is also hoisted at the yardarm to indicate that a general court-martial or a court of inquiry is in session. It is hoisted when the court meets and is hauled down when the court adjourn. When displayed from the jackstaff, the union jack is half-masted when the ensign is half-masted. It is not dipped, however, when the ensign is dipped in return for such honor being rendered it. The union jack is flown in boats as follows: When a diplomatic representative of the United States of or above the rank of charge d'affaires is embarked in a boat of the U.S. Navy and is within the waters of the country to which he/she is accredited When a governor general or governor commis- sioned as such by the President is embarked in a boat in an official capacity and is within the area of jurisdiction (for example, the Governor of the Virgin Islands) PERSONAL FLAGS AND COMMAND PENNANTS LEARNING OBJECTIVES: Identify procedures for the displaying of personnel flags and command pennants from ships, shore commands, vehicles, and aircraft. Explain the use of the commission pennant. Figure 10-2 shows personal flags, personal command pennants, and several miscellaneous flags and pennants. The distinctive mark of a ship or craft in commission in the Navy is either a commission pennant, a personal flag, or a command pennant of an officer of the Navy eligible for command at sea. The distinctive mark of a Navy hospital ship in commission is the Red Cross flag. Only one distinctive mark is displayed by a ship or craft at one time. If a personal flag, including that of a civil official, or command pennant goes up, the commission pennant comes down. Except as prescribed in Navy Regulations for certain occasions of ceremony, the distinctive mark must remain at the after masthead day and night or, in a mastless ship, from the loftiest and most conspicuous hoist. Ceremonial occasions may require the shifting of the distinctive mark to another masthead or to the starboard yardarm. DISPLAY OF PERSONAL FLAGS AND COMMAND PENNANTS A flag officer or unit commander afloat must display his/her personal flag or command pennant from his/her flagship. At no time must he/she display it from more than one ship. When a flag officer, eligible for command at sea, is embarked for passage in a ship of the Navy, his/her personal flag must be displayed from such ship unless there is already displayed a personal flag of an officer his/her senior. There are any number of civil officials entitled to show personal flags that go with their offices. The flags of interest to a Signalman, however, are those belonging to civil officials whose personal flags are authorized for display during official visits. (Visits are discussed later in this chapter.) Personal flags of principal civil officials are shown in figure 10-3. 10-6
