  COMMAND AND SUPPORT RELATIONSHIPS FOR HUMINT OPERATIONS
  4-13. Clear command and support relationships are fundamental in
  organizing for all operations. These relationships identify responsibilities
  and authorities among subordinate and supporting units. The commander
  designates command and support relationships within his authority to
  weight the decisive operation and support his scheme of maneuver. Some
  forces available to a commander are given command or support relationships
  that limit his authority to prescribe additional relationships. Command and
  support relationships carry with them varying responsibilities to the
  subordinate unit by parent and gaining units. By knowing the inherent
  responsibilities, a commander may organize his forces to establish clear
  relationships.
  4-14. Command relationships establish the degree of control and
  responsibility commanders have for forces operating under their tactical
  control (TACON). When commanders establish command relationships, they
  determine if the command relationship includes administrative control
  (ADCON). Table 4-2 shows Army command and support relationships and
  Table 4-3 shows joint command relationships chart from FM 3-0 (derived
  from JP 0-2 and JP 3-0).
  4-15. Support relationships define the purpose, scope, and effect desired
  when one capability supports another. Support relationships establish
  specific responsibilities between supporting and supported units. Table 4-2
  shows Army command and support relationships and Table 4-4 shows joint
  support relationships from FM 3-0 (derived from JP 0-2 and JP 3-0).
  HUMINT REQUIREMENTS MANAGEMENT
  4-16. The G2/S2 is responsible for RM. He uses the requirements
  management (RM) process to orchestrate the actions of the unit’s organic and
  supporting ISR capabilities into a unified effort to gain situational
  understanding and answer the commander’s PIRs. Through centralized
  planning and decentralized execution, RM optimizes the integration of ISR
  operations into the commander’s scheme of maneuver and fire and into the
  unit’s long- and short-range planning. Control mechanisms within the RM
  structure facilitate the identification of information shortfalls and the
  redirection of ISR assets to new intelligence production, reconnaissance, or
  surveillance missions.
