  1-91. According to the Global Force Management Implementation Guidance, unless otherwise directed by
  the President or the Secretary of Defense, all forces operating in the geographic area assigned to a combatant
  commander are assigned or attached to that combatant commander. A force assigned or attached to a
  combatant commander may be transferred from that commander to another combatant commander only when
  directed by the Secretary of Defense and approved by the President. The Secretary of Defense specifies the
  command relationship the gaining commander will exercise (and the losing commander will relinquish).
  Establishing authorities for subordinate unified commands and JTFs may direct the assignment or attachment
  of their forces to those subordinate commands and delegate the command relationship. (See figure 1-4 on
  page 1-20. See JP 1 for more information on assigned or attached forces.)
