  AUTHORITIES AND RESPONSIBILITIES
  1-62. The remainder of this chapter discusses the command authority of the CCDR, Army Title 10
  sustainment requirements, and Army assigned executive agent (EA) responsibilities. Army command and
  support relationships are discussed in detail in chapter 2.
  COMMAND AUTHORITY OF COMBATANT COMMANDERS
  1-63. Title 10, United States Code (USC), Section 162 specifies the force structure prescribed for each
  CCMD as follows: “(a) Assignment of Forces.- (1) As directed by the Secretary of Defense, the Secretaries
  of the military departments shall assign specified forces under their jurisdiction to unified and specified
  combatant commands or to the United States element of the North American Aerospace Defense Command
  to perform missions assigned to those commands. The Secretary of Defense shall ensure that such
  assignments are consistent with the force structure prescribed by the President for each combatant command.
  (2) A force not assigned to a combatant command or to the United States element of the North American
  Aerospace Defense Command under paragraph (1) shall remain assigned to the military department
  concerned for carrying out the responsibilities of the Secretary of the military department concerned as
  specified in section 7013, 8013, or 9013 of this title, as applicable. (3) A force assigned to a combatant
  command or to the United States element of the North American Aerospace Defense Command under this
  section may be transferred from the command to which it is assigned only- (A) by authority of the Secretary
  of Defense; and (B) under procedures prescribed by the Secretary and approved by the President. (4) Except
  as otherwise directed by the Secretary of Defense, all forces assigned to a unified combatant command shall
  be under the command of the commander of that command. The preceding sentence applies to forces assigned
  to a specified combatant command only as prescribed by the Secretary of Defense. (b) Chain of Command-
  Unless otherwise directed by the President, the chain of command to a unified or specified combatant
  command runs- (1) from the President to the Secretary of Defense; and (2) from the Secretary of Defense to
  the commander of the combatant command.”
  1-64. Title 10, USC, Section 164 specifies the CCDR's responsibility for authoritative direction for logistics
  (doctrinally referred to as directive authority for logistics [DAFL]). Paragraph C1 states: “Unless otherwise
  directed by the President or the Secretary of Defense, the authority, direction, and control of the commander
  of a combatant command with respect to the commands and forces assigned to that command include the
  command functions of -(A) giving authoritative direction to subordinate commands and forces necessary to
  carry out missions assigned to the command, including authoritative direction over all aspects of military
  operations, joint training, and logistics; (B) prescribing the chain of command to the commands and forces
  within the command; (C) organizing commands and forces within that command as he considers necessary
  to carry out missions assigned to the command;(D) employing forces within that command as he considers
  necessary to carry out missions assigned to the command; (E) assigning command functions to subordinate
  commanders; (F) coordinating and approving those aspects of administration and support (including control
  of resources and equipment, internal organization, and training) and discipline necessary to carry out
  missions assigned to the command; and (G) exercising the authority with respect to selecting subordinate
  commanders, selecting combatant command staff, suspending subordinates, and convening courts-martial,
  as provided in subsections (e), (f), and (g) of this section and section 822(a) of this title, respectively.”
  1-65. Combatant command (command authority) (COCOM) over assigned forces is vested only in the
  commanders of CCMDs by Title 10, USC and cannot be delegated or transferred. This authority over
  assigned forces includes DAFL, which gives the CCDR the authority to organize logistics resources within
  theater according to operational needs. The President or Secretary of Defense may extend this authority to
  attached forces when transferring forces for a specific mission and should specify this authority in the
  establishing directive or order.
  Directive Authority for Logistics
  1-66. The CCDR uses DAFL to assign responsibility for execution of EA and lead Service responsibilities,
  and to make other special arrangements such as assigning common-user support or common-user logistics
  (CUL) to a Service or agency. Directive authority for logistics is the combatant commander authority to issue
  directives to subordinate commanders to ensure the effective execution of approved operation plans, optimize
