  PROVIDE WARNINGS
  5-62. Across the range of military operations, various collection assets provide early warnings of threat action.
  As analysts screen incoming information and message traffic, they provide the commander with advanced
  warnings of threat activities or intentions that may change the basic nature of the operation. These warnings
  enable the commander and staff to quickly reorient the force to unexpected contingencies and to shape the OE.
  5-63. Analysts can use analytic techniques and their current knowledge databases to project multiple
  scenarios and develop indicators as guidelines for providing warning intelligence. An indicator is, in
  intelligence usage, an item of information that reflects the intention or capability of an enemy and/or
  adversary to adopt or reject a course of action (JP 2-0). Analysts project future events and identify event
  characteristics that can be manipulated or affected. Characteristics that cannot be manipulated or affected
  should be incorporated into unit SOPs as warning intelligence criteria. (See ATP 2-01 and ATP 2-01.3 for
  doctrine on indicators.)
