EXECUTIVE METHOD The executive method is used when it is desired to execute a tactical message at a given instant; that is, to ensure that two or more units take action at the same moment.  An  abbreviated  plaindress  format  is normally  used  for  transmitting  messages  by  the executive method. When conditions are good, it is necessary to have all stations called acknowledge receipt  of  tactical  message.  In  these  circumstances, only  those  call  signs  preceding  the  proword  OVER receipt  for  the  message.  Messages  sent  by  the executive method are never to have a time group included  in  the  message  ending.  There  are  two executive  methods: Delayed Immediate Delayed Executive Method A tactical message sent by the delayed executive method  will  carry  the  warning  proword  EXECUTE TO   FOLLOW   in   the   message   instructions, immediately preceding the text. The executive signal w i l l    b e    s e n t    l a t e r    i n    t h e    f o r m    S T A N D BY—EXECUTE, the latter word being the instant of execution. The text of the message being executed must be repeated prior to the transmission of the proword  EXECUTE  when: 1. It is a portion of, or one of, several outstanding signals;  or 2. A considerable time has elapsed between the transmission of an EXECUTE TO FOLLOW message and the transmission of the executive signal. M15B  transmits: All stations respond in alphabetical order to full call Example: Six  Charlie—THIS  IS  Five  Bravo—EXECUTE TO   FOLLOW—Corpen   Mike   One   One Two—OVER signs: Six  Two—ROGER—OUT Nine   Eight—ROGER—OUT Three   Four—ROGER—OUT After a considerable period of time has elapsed M15B transmits: Six Charlie—THIS IS Five Bravo—Corpen Mike One  One  Two—  Standby—EXECUTE—Three Four—OVER Three  Four  responds: Three   Four—ROGER—OUT Immediate  Executive  Method In cases of urgency, the executive signal may be transmitted in the final instruction element of the message. This type of message does not allow stations to  obtain  verifications,  repetitions,  acknowledge- ments,   or   cancellations   before   the   message   is executed. Messages made by the immediate executive method should be in plain language, or should be limited  to  basic  TURN,  SPEED,  and  CORPEN signals. The   warning   proword   is   IMMEDIATE EXECUTE. The text is sent twice, separated by the proword I SAY AGAIN. The executive signal is sent in the final instructions. Example: M15B  transmits: Six Charlie—THIS IS Five Bravo—IMMEDIATE EXECUTE—BREAK—Turn     Port—Tack-Speed One  Four—I  SAY  AGAIN—Turn  Port—Tack— Speed  One  Four—Stand  by—EXECUTE—Nine Eight—Three   Four—OVER B198  and  D234  transmit: Nine   Eight—ROGER—OUT Three   four—ROGER—OUT BEADWINDOW Beadwindow is a simple, rapid procedure for use by circuit operators to police the security of insecure voice networks.  It  brings  to  the  immediate  attention  of operators  the  fact  that  an  Essential  Element  of  Friendly Information (EEFI) has been disclosed on the circuit. Additionally, the beadwindow report serves to alert other operators on the net of the EEFI disclosure and thus acts as  an  educational  aid,  producing  increased  security awareness among operators and an overalI improvement in the security of insecure voice radio. The beadwindow procedure uses a code word (beadwindow)  and  a  number  combination,  which  are 4-22
