  Theater Sustainment Command
  4-73. The Theater Sustainment Command (TSC) is the Army’s organization for the integration and
  synchronization of sustainment in a theater. The TSC connects strategic enablers to tactical formations. It is
  a theater-committed asset to each theater army, and it focuses on Title 10, USC support of Army forces for
  theater security cooperation and the CCDR’s daily operational requirements.
  4-74. TSCs execute sustainment operations through their assigned and attached units while integrating and
  synchronizing sustainment operations across an AOR. They have four operational responsibilities to forces
  in theater: theater opening, theater distribution, sustainment, and theater closing. The task-organized TSC is
  tailored to provide operational-level sustainment support within an assigned AOR. It integrates and
  synchronizes sustainment operations for the theater army, including all Army forces forward stationed,
  transiting, or operating within an AOR. The TSC coordinates Title 10, USC; ASOS; DOD executive agency;
  and lead Service responsibilities across the entire theater. (See ATP 4-94 for more information on the TSC.)
  Military Intelligence Brigade-Theater
  4-75. The MIB-T is usually assigned to the combatant command with OPCON delegated to the theater army.
  It provides mission command for the theater army’s information collection and intelligence analysis
  capabilities across all intelligence disciplines, integrating theater and national architectures and data to
  support the theater army’s daily operations requirements and preparation for contingency operations. The
  theater army headquarters specifically relies on the MIB-T for threat characteristics, intelligence estimates,
  threat and civil considerations, data services, intelligence architecture development and maintenance, and
  all-source intelligence products. These efforts support theater army planning requirements, including
  development of Army plans supporting the CCP and maintenance of OPLANs and contingency plans.
  4-76. The MIB-T serves as the intelligence anchor point for deploying forces, providing theater-specific
  expertise and support. It maintains a regional intelligence architecture that deploying and theater-aligned
  units can access. This allows units to tailor mission planning and training and effectively leverage the broader
  intelligence enterprise. The MIB-T’s regional focus provides continuity and cultural context to its analytic
  intelligence products. The brigade can collect, analyze, and track the threat characteristics and doctrine of
  theater state and non-state actors over many years, providing indications and warnings of changes in an
  operational environment. This allows it to create and maintain a valuable database of intelligence regarding
  persons of interest and the evolving doctrine and capabilities of regional military forces. (See FM 2-0 for
  more information on the MIB-T.)
  Theater Aviation Elements
  4-77. Theater aviation support is executed by theater aviation brigades, theater airfield operations groups,
  and theater aviation sustainment maintenance groups. Each theater aviation brigade can conduct assault or
  general support aviation tasks in support of the theater and its subordinate commands, but it requires
  augmentation with attack aviation or unmanned aircraft system (UAS) units to conduct attack,
  reconnaissance, and security operations. Combat aviation brigades may also support theater aviation
  operations with lift, attack, and UAS capabilities. Theater airfield operations groups provide air traffic
  services, conduct airfield management operations, and support RSOI requirements for aviation assets. The
  theater aviation sustainment group is resourced to provide aviation sustainment maintenance and limited
  depot sustainment support throughout the theater AO. (See FM 3-04 for more information on aviation
  brigades and groups.)
  Army Air and Missile Defense Command
  4-78. The Army air and missile defense command (AAMDC) is the highest echelon for air defense artillery
  units. It is usually under OPCON of the theater army, or land component command if designated, with the
  AAMDC commander serving as the theater Army AMD coordinator. The AAMDC is also usually in direct
  support of the theater air force, or air component command if designated, with the AAMDC commander
  serving as the theater deputy area air defense commander. The AAMDC participates in theater exercises and
  integrates with joint and multinational partners in all aspects of AMD operations. It provides assets and
  coordinates coverage to protect forward-positioned joint and Army forces, and critical infrastructure, from
