  SECTION IV – DEFENSIVE CONTROL MEASURES
  7-94. A control measure is a means of regulating forces or warfighting functions. Control measures provide
  control without requiring detailed explanations. Control measures can be permissive (which allows
  something to happen) or restrictive (which limits how something is done). Some control measures are
  graphic. A graphic control measure is a symbol used on maps and displays to regulate forces and warfighting
  functions. (See ADP 1-02 for illustrations of graphic control measures and rules for their use.)
  COMMON DEFENSIVE CONTROL MEASURES
  7-95. Control measures provide the ability to respond to changes in the situation. They allow the defending
  commander to concentrate combat power at the decisive point. Commanders use the minimum number to
  control their units and tailor their use to the higher commander’s intent. Figure 7-7onpage 7-25illustrates a
  BCT’s use of the following control measures:
