  6-21. The exercise of mission command is based on mutual trust, shared understanding, and purpose.
  Commanders understand that some decisions must be made quickly at the point of action. Therefore, they
  concentrate on the objectives of an operation, not how to achieve it. Commanders provide subordinates
  with their intent, the purpose of the operation, the key tasks, the desired end state, and resources.
  Subordinates then exercise disciplined initiative to respond to unanticipated problems. Every Soldier must
  be prepared to assume responsibility, maintain unity of effort, take prudent action, and act resourcefully
  within the commander’s intent. Successful mission command of FM operations hinges on subordinate FM
  leaders at all echelons exercising disciplined initiative within the commander’s intent to accomplish
  missions. Mission command requires a command atmosphere of knowledge sharing, trust and mutual
  understanding. Mission command consists of six principles:
  * Build cohesive teams through mutual trust.
  * Create shared understanding.
  * Provide a clear commander’s intent.
  * Exercise disciplined initiative.
  * Use mission orders.
  * Accept prudent risk.
  6-22. Mission command of FM organization and functions, like command of land forces, rarely fall
  directly under the direct control of any one commander or FM leader. The senior FM leader within theater,
  the ASCC G-8 or JTF C-8 (corps or Div G-8), relies on the independent actions of subordinate sustainment
  and FM leaders in the planning and execution of FM operations.
  6-23. As previously depicted in figure 1-6 on page 1-14, FM theater operations are commanded and
  controlled through a network of explicit command and staff relationships and implicit coordination between
  staffs that exist from the TA G-8 down to the lowest tactical FM unit – the FMSD. In between these levels
  of command, various FM unit and staff personnel within multiple organizations (e.g., TSC, FMSC, ESC,
  SUST BDE and FMSUs) integrate, synchronize, coordinate and manage FM operations throughout the
  theater in order to provide full spectrum FM support to the theater commander’s mission. Tactical FM units
  fall under the command and control of the theater sustainment command. The FMSC is a subordinate
  operational element of the TSC and provides technical oversight of all theater tactical FM units executed by
  tactical FMSUs and FMSDs. This coordination includes providing technical FM policy and guidance on
  FM procedures, systems and FM reporting requirements.
  6-24. The SUST BDE has mission command over the FMSUs and FMSDs. It relies on the ESC FM SPO
  to integrate and coordinate its FM operations. The SUST BDE also ensures the provision of requisite FM
  support to units within the SUST BDE’s AO. The Sustainment Brigade Commander (SUST BDE CDR)
  may place the FMSU under the mission command of the STB. The ESC FM SPO communicates directly
  with the FMSC when coordinating FM operations. Regardless of where the FM units are placed within the
  SUST BDE, the SUST BDE CDR bears overall responsibility for compliance of FM units with established
  internal controls and works with the FMSC to ensure that those FM units under his or her command and
  control do in fact comply with all applicable laws and regulations governing FM operations.

  MANAGEMENT SUPPORT OPERATIONS (FM SPO)
  6-25. As stated earlier, the FM SPO section has undergone significant structural changes since the previous
  edition of this manual. Now, FM SPO personnel are only at the ESC level. The ESC FM SPO is critical to
  the successful execution of tactical FM operations within theater as this staff section plans, coordinates, and
  synchronizes FM disbursing support for all units within an entire ESC’s assigned AO. The FM SPO must
  possess the necessary experience and knowledge in FM operations in order to be a principal FM asset to the
  ESC commander.
  6-26. The ESC FM SPO is key to the successful integration of FM operations and FM capabilities. FM
  support must remain responsive and retain the necessary flexibility to meet the ever-changing requirements
  of U.S. forces in the ESC AO. The ESC FM SPO evaluates the adequacy of support throughout the AO by
  analyzing workload data, supporting population size, and making recommendations to maximize efficiency
