  FRAGMENTARY ORDER
  B-7. A fragmentary order is an abbreviated form of an OPORD used to make changes in missions to units
  or to inform them of changes in the tactical situation. Like WARNORDs, these are usually brief oral or
  written messages. Mission orders are a form of a fragmentary order that provide experienced leaders with the
  essentials of an order: their mission or a change to a previously issued mission. Fragmentary orders may be
  oral, written, or graphic; in all instances, they are brief. An example of fragmentary order is presented in
  figure B-2 on page B-5.
