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
