  Civil Affairs Graphic Control Measures
  This appendix shows a variety of symbols and graphic control measures related to CA and
  CA tactical mission tasks. The appendix does not attempt to produce all conceivable
  combinations for CA symbols or control measures, but it shows several examples of each
  type as a starting point.
  OVERVIEW
  D-1. A military symbol is a graphic representation of a unit, equipment, installation, activity, control measure, or
  tactical task relevant to military operations that is used for planning or to represent the common operational picture
  on a map or overlay. Military symbols are governed by the rules in MIL-STD-2525D. FM 1-02.2 also provides an
  extensive number of icons and modifiers for building a variety of framed symbols.
  MODIFIERS FOR FRAMED SYMBOLS
  D-2. A modifier provides an abstract pictorial or alphanumeric representation displayed inside the framed symbol
  in conjunction with a main icon. It provides information about the icon (unit, equipment, installation, or activity)
  being displayed. Sector 1 modifiers (or modifiers placed above the main icon) show a specific function that the
  unit is organized and equipped to perform. Sector 2 modifiers (or modifiers placed below the main icon) reflect
  the mobility, size, range, or altitude of unit equipment, or an additional capability of the unit.
  AMPLIFIERS FOR FRAMED SYMBOLS
  D-3. An amplifier provides additional information about the symbol being shown and is displayed outside the
  frame. To avoid cluttering the display, only essential amplifier fields should be used. The amplifier location in the
  figure E-1 have changed from previous editions of FM 1-02.2. The locations also vary from MIL-STD-2525D.
  Figure D-1 and table D-1, pages D-2 through D-3, standardize the field locations of additional information.
