where does the term bravo zulu come from
Bravo Zulu According to the "Navy Data" reference website operated by the U.S. Navy: "The term BRAVO ZULU originates from the Allied Tactical Publication 1 (ATP 1),[1] an Allied military maritime tactical signals publication, which in the aggregate is For Official Use Only, and can also be found in Multinational Maritime Tactical Publication 2 (MTP 2).[2] Signals are sent as letters and/or numbers, which have meanings by themselves sometimes or in certain combinations. A single table in ATP 1 is called 'governing groups,' that is, the entire signal that follows the governing group is to be performed according to the 'governor.' The letter 'B' indicates this table, and the second letter (A through Z) gives more specific information. For example, 'BA' might mean 'You have permission to . . .' (do whatever the rest of the flashing light, flag hoist or radio transmission says). 'BZ' happens to be the last item of the governing groups table and it means 'well done'." [3][4]
