  Field Field Title Description
  The part of the symbol that represents the unit symbol, or object function
  A Symbol icon
  (modifier).
  B Echelon This is a unit symbol that identifies command level.
  C Quantity This identifies the number of items present.
  H Additional information This content is implementation specific.
  N Hostile (enemy) The letters ENY denote hostile control measure symbols.
  Direction of movement Identifies the direction of movement (or intended movement) of an object.
  Q
  indicator
  For points and chemical, biological, radiological, and nuclear events,
  S Offset location indicator
  used for placing an object away from its actual location.
  T is used to differentiate points by numbering, lettering, or a combination
  of both. T1 may be used to include the unit designation.
  Notes:
  1. In some cases, this tactical symbol may require multiple instance of a T
  T, T1 Unique designation
  amplifier to fully create or represent an object.
  2. T1 may be used if the field used is displayed more than once in a
  tactical symbol.
  3. The unnumbered fields should be filled before the numbered fields.
  V Type Indicates type of equipment or nuclear weapon type.
  W identifies the start date-time group, and it can be displayed alone or
  in conjunction with W2 to identify the projected date-time group end
  date. The W represents an alphanumeric designator for displaying a
  date-time group (DDHHMMSSZMONYYYY), or O/O, for on order.
  When W and W2 are used in conjunction, this identifies the time
  control measure is in effect.
  W,
  Date-time group The date-time group is composed of a group of six numeric digits with a
  W2
  time zone suffix, and the standardized three-letter abbreviation for the
  month, followed by four digits representing the year. The first pair of digits
  represents the day; the second pair, the hour; and the third pair, the
  minutes. The last four digits, after the month, represent the year. For
  automated systems, two digits may be added before the time zone suffix
  and after the minutes to designate seconds.
  Displays the minimum, maximum, or specific altitude (in feet or meters)
  X Altitude or depth in relation to a reference datum and the flight level or depth for
  submerged objects (in feet below sea level).
  Y Location Displays the location of a symbol in degrees, minutes, and decimal minutes.
  An alphanumeric amplifier that displays a minimum, maximum, or specific
  AM Distance
  distance (including range, radius, width, or length) in meters.
  A numeric amplifier that displays an angle measured from true north to any
  AN Azimuth
  other line—in degrees.
  A six-character text modifier used in fire support operations to uniquely
  designation targets where characters 1 and 2 are alphabetic, and characters
  AP Target number
  3 through 6 are numeric.
  Example: AANNNN (where A is alphabetic, and N is numeric)
