From the NRA rule book, modified for static targets at 100 yards.

(B) RAPID FIRE - When ready to start a match, the Chief Range Officer commands, "RELAY (number), MATCH (number), (or naming the match), TAKE YOUR POSITIONS ON THE FIRING LINE. DO NOT HANDLE YOUR RIFLES. YOUR PREPARATION PERIOD WILL START IN TWO MINUTES." Competitors take their places on their firing points. After two minutes the command is given, "YOUR PREPARATION PERIOD WILL BEGIN NOW." At the end of three minutes the command is given, "THE PREPARATION PERIOD HAS ENDED." If sighters are allowed in the match the following commands apply. "YOU WILL NOW HAVE A SIGHTER PERIOD OF TWO MINUTES FOR TWO SLOW FIRE SIGHTERS, WITH ONE ROUND LOAD. IS THE FIRING LINE READY? THE FIRING LINE IS (IS NOT) READY." If the firing line is not ready then wait for the problem to be resolved and then, "RESUMING COMMANDS. THE FIRING LINE IS READY. YOUR TIME BEGINS AND YOU MAY FIRE WHEN READY." After two minutes "CEASE FIRE, UNLOAD. YOUR SIGHTER PERIOD HAS ENDED. YOUR NEXT STRING OF FIRE WILL BE RAPID FIRE (SITTING/KNEELING) (OR PRONE) FROM STANDING; TEN SHOTS FIRED IN A TIME LIMIT OF (60) OR (70) SECONDS. SHOOTERS STAND."

(1)  "WITH THE BOLT REMAINING OPEN, LOAD." When all rifles appear to be loaded the commands ask, "IS THE LINE READY?" Any competitor who is not ready at this time, or whose target is not ready, will raise his arm and call "NOT READY ON TARGET (number)" A Range Officer investigates and either assists the competitor to correct the cause of the delay, or removes the competitor safely from the firing line to fire on an alibi relay so as not to delay the start of firing. After observing, or receiving a signal that the problem is resolved or making a decision to continue without further delay, "THAT COMPETITOR(S) WILL FIRE ON AN ALIBI RELAY. RESUMING COMMANDS, THE LINE IS READY." The following sequence of preparatory commands is given, stopped only by sudden inability of the range to operate properly or by safety considerations: "READY ON THE RIGHT" three second pause. "READY ON THE LEFT". Three second pause. "READY ON THE FIRING LINE.". The start of time will be signaled either verbally or by a short blast on a whistle.

(2) At the end of time allowed another verbal signal or another short blast on a whistle will be signaled as appropriate. The command is given "CEASE FIRE-UNLOAD. REMAIN IN POSITION UNTIL THE LINE IS CLEARED. ARE THERE ALIBIS OR SAVED ROUNDS ON THE RIGHT? " ALIBIS OR SAVED ROUNDS ON THE LEFT?". "IS THE LINE CLEAR?" This means that all rifles on the line are unloaded, detachable magazines removed and all bolts are open. The Chief Range Officer announces "YOU WILL NOW HAVE TWO MINUTES TO RELOAD YOUR MAGAZINES OR CLIPS".

(3) The Chief Range Officer announces "FOR YOUR SECOND STRING OF RAPID FIRE (SITTING/KNEELING) (OR PRONE) FROM STANDING;  TEN SHOTS FIRED IN A TIME LIMIT OF(60) or(70) SECONDS; SHOOTERS STAND." and repeats the procedure listed above in this narrative (B),  for starting a rapid fire match from that point in this narrative. The procedure continues in this narrative until the point is reached (2) where time allowed for the string of rapid fire has ended and on ranges that have pits the targets are withdrawn into the pits. The command is then given "CEASE FIRE - UNLOAD. PLACE THE OPEN BOLT INDICATOR IN YOUR RIFLE. REMAIN IN POSITION UNTIL THE LINE IS CLEARED. ARE THERE ALIBIS OR SAVED ROUNDS ON THE RIGHT? ALIBIS OR SAVED ROUNDS ON THE LEFT?" Again transfer information on saved or late rounds to the pits. Then, "IS THE LINE CLEAR?" This now means all rifles are unloaded, detachable magazine removed and open bolt indicators are properly in place in the rifle. Upon receiving confirmation from Range Officers that all rifles are clear say, "THE LINE IS CLEAR. YOU WILL NOW MOVE OUT OF POSITION AND REMOVE ALL OF YOUR EQUIPMENT FROM THE FIRING POINT. YOU MAY STAND BY TO RECEIVE SCORES AND GROUPS. ALL PERSONNEL RETURN BEHIND THE FIRING LINE." When all personnel are behind the firing line you will proceed to the point at the beginning of this narrative (B) and continue in the narrative (B) from that point to start your next relay in the rapid fire match.

Note: The tempo used to deliver these commands will establish the flow of your match. The best Range Officers (tower talkers) monitor the competitors as they are responding to commands. Then they adjust their tempo of the commands to keep the match moving crisply without causing undue stress on the competitors. Common sense, compassion, a keen sense of pace and a good knowledge of this rule book are characteristics displayed by talented Range Officers (tower talkers).
