  DATE AND TIME GROUP
  2-5. The date and time group line of a message identifies the message origination time. Many report and
  message formats require the date and time group for additional information. Regardless of where the date
  and time group is used in a report or message, it is expressed as DDHHMM(X) MMMYY where:
  (cid:122) DD indicates the day of the month.
  (cid:122) HH indicates the hour of the day using the 24-hour clock.
  (cid:122) MM indicates the minutes within the hour.
  (cid:122) X indicates the alphabetic character that denotes the time zone. In written messages, the time zone
  is followed by a space.
  (cid:122) MMM indicates the first three letters of the month of the year. In written messages, all letters are
  in uppercase.
  (cid:122) YY indicates the last two digits of the year.
  2-6. For example, 3 p.m. local time on 16 July 2018 is expressed as “161500(L) JUL18.” In a voice
  message, say: “one six one five hundred lima (or local) July one eight.”
  UNITS
  2-7. The first line of a format requiring an entry for “unit” is to identify the unit making the report.
  Occasionally, a subunit line is also provided for reporting information from or about subunits. Unit standard
  operating procedures dictate the format for the unit name (for example, the call sign).
  LOCATIONS
  2-8. Use the military grid reference system (MGRS) to express all locations unless the format specifies a
  different coordinate system such as latitude and longitude (LAT/LONG) or universal transverse Mercator
  (UTM). A complete MGRS location includes a longitudinal zone designated by a number (for example, 32),
  a latitudinal band designated by a letter (for example, T), a 100,000 meter grid square designated by two
  letters (for example RW), and a grid coordinate designated by digits. The UTM grid zone designator consists
  of the longitudinal zone and latitudinal band (for example, 32T). The MGRS grid zone designator is the two
  letter 100,000 meter designator (for example, RW) (see TC 3-25.26 for further details on MGRS).
  2-9. Send all locations as six digit grids preceding the 100,000 meter grid square designator (for example
  “RW121972”) unless instructions state otherwise. To avoid confusion, do not transmit the zone and band
  indicators unless requested or required in the message format. If requestors require locations expressed to a
  greater precision than a six digit coordinate, they must specify the required detail prior to the information
  exchange.
  ADDITION OR DELETION OF LINE NUMBERS
  2-10. Originators of voice messages complete only the lines required to pass essential information and omit
  lines with no information, unless a negative report is necessary. Units may add lines or repeat lines to
  complete information requirements. While actual message transmissions may vary slightly from formats in
  this publication, to maintain standardization across the U.S. Army, do not delete lines from message formats
  when reproducing them in unit standard operating procedures to maintain standardization across the U.S.
