Information Sheet Number: 1.14
As with ship handling, standard phraseology is an extremely important part of any gun fire exercise. Gunnery Officers must ensure all personnel involved with gun fire exercsies know and understand the proper terminology and phraseology associated with gun firings. This is especially important in the event of a casualty. There can be no confusion among key watch standers and personnel regarding gunnery commands and status reports. Standard phraseology is the key to avoiding any confusion.
(a) Ship specific Combat Systems Doctrine
1. Just as in ship control standard commands, misinterpretation of gun order commands can severely endanger a ship and crew.
2. Standardization of all commands and reports used in controlling and firing weapons is extremely important. Therefore, all personnel must have a thorough knowledge of the commands and reports with no room for misinterpretation.
3. Whenever a ship is conducting training, the training should be held at the level of an actual firing exercise.
a. Standardized phraseology should be the only terminology used.
b. Verbatim repeat backs should be enforced at all times.
