  * Promoting rationalization, standardization, enhanced interoperability, and other defense
  cooperation measures.
  * Liaison functions exclusive of advisory and training assistance.
  COMBATANT COMMAND
  1-81. In accordance with the Unified Command Plan, combatant commands are established by the President,
  through the Secretary of Defense, with the advice and assistance of the CJCS. Combatant commands are
  assigned AORs and work in support of, and in close coordination with U.S. embassies within their AORs to
  achieve U.S. national interests and global end states as detailed in the NSS and other guidance documents.
  This operational relationship is primarily related to the SC organization’s execution of the combatant
  command’s theater campaign plan with the host country’s military. The combatant command and the
  ambassador ensure that the SDO/DATT does not receive conflicting guidance, instructions, or priorities. If
  conflicting guidance occurs, the SDO/DATT must seek clarification or resolution. The SDO/DATT chief is
  uniquely able to understand both the combatant command and the ambassador, balance their respective
  priorities, and leverage their resources. A key challenge for the SDO/DATT is to respond to the direction of
  the ambassador while at the same time satisfying coordination and support requirements from the combatant
  command.
  1-82. DOD’s strategic end states support the NSS to ensure the strategic end states complement and support
  foreign policy objectives. As part of theater campaign planning, combatant commands develop country plans
  that align with each ambassador’s goals within the AOR because the activities and investments typically
  occur at the country level. Combatant commands exercise authority for force protection over all DOD
  personnel (including their dependents) assigned, attached, transiting through, or training in the combatant
  command’s AOR, except for those for whom the COM retains security responsibility. This force protection
  authority enables combatant commands to change, modify, prescribe, and enforce force protection measures
  for covered forces. Combatant commands also provide directive authority over forces conducting exercises
  in that AOR.
  THEATER ARMY
  1-83. The theater army is the ASCC to the combatant command and fulfills all requirements of a Service
  component for Army forces assigned or attached to the combatant command. The theater army’s primary
  responsibilities are—
  * Execute combatant commander’s daily operational requirements.
  * Provide administrative control of Army forces.
  * Set and maintain the theater.
  * Set and support the operational areas.
  * Plan and coordinate the consolidation of gains in support of joint operations.
  * Exercise command and control over Army forces in theater.
  * Perform joint roles in limited scope, scale, and duration.
  1-84. ATP 3-93 depicts the organization of the theater army main command post. The theater army SC
  division normally resides within the assistant chief of staff G-3. It normally consists of a headquarters section,
  a plans and exercises section, and an international military affairs section with the total division consisting
  of eight to ten personnel and normally led by a colonel or lieutenant colonel (See figure 1-3 on page 1-16).
