Times relative to the designation are indicated with +/−[Arabic numeral] after the letter, replacing -day or -hour with a count of the same unit: "D−1" (the day before D-Day), "L+9" (9 hours after L-Hour) etc. [citation needed] In less formal contexts, the symbol or numeral may be spelled out: "D minus 1" or "L plus nine." [citation needed ...
The 24-hour clock is used in military, public safety, and scientific contexts in the United States. [4] It is best known for its use by the military and is therefore commonly called "military time". In U.S. military use, 24-hour time is traditionally written without a colon (1800 instead of 18:00).
In communications messages, a date-time group (DTG) is a set of characters, usually in a prescribed format, used to express the year, the month, the day of the month, the hour of the day, the minute of the hour, and the time zone, if different from Coordinated Universal Time (UTC).

An air tasking order (ATO) is a means by which the Joint Forces Air Component Commander (JFACC) controls air forces within a joint operations environment. The ATO is a large document written in United States Message Text Format (USMTF) that lists air sorties for a fixed 24-hour period, with individual call signs, aircraft types, and mission types (e.g. close air support or air refueling).
Instead, letter designations are randomly assigned using BATCO sheets, and appear on CEIs (communication electronic instructions), and change along with the BATCO codes every 24 hours. This, together with frequency changes and voice procedure aimed at making every unit sound the same, protects the military against simple traffic analysis and ...
