  THEATER MOVEMENT CONTROL ELEMENT
  2-53. The theater movement control element (TMCE) is a multifunctional theater-level center allocated to a
  TSC. The TMCE provides movement management, container management, highway regulation, and
  coordination for personnel and materiel movements. It provides staff augmentation to establish and refine
  distribution networks during operations, manage containers (commercial, unit, and DOD), and develop
  movement programs for the distribution of sustainment stocks within the AO or JOA as required. The TMCE
  coordinates with strategic partners to locate and identify strategic ports of entry into the AOR. It plans,
  monitors, and coordinates the intertheater movement program to facilitate military forces moving during
  crisis below armed conflict, and it supports large-scale combat operations by committing air and ground
  transportation assets in the support of reception, staging, and onward movement of forces entering into
  theater. The TMCE also plans, monitors, and implements the intratheater movement program in accordance
  with CCDR priorities. For additional information on the TMCE, see ATP 4-93.
  THEATER PETROLEUM AND WATER GROUP
  2-54. The theater petroleum and water group is normally attached to a TSC. It supports a theater Army in
  establishing, managing, and conducting petroleum and water operations. The petroleum and water group is
  responsible for planning and providing command and control of the theater petroleum and water units
  assigned to build theater stocks, distribution systems, and quality surveillance support structure. It has a SPO
  section that coordinates, manages, and synchronizes all bulk petroleum in the theater or corps. For additional
  information see ATP 4-43.
  THEATER PETROLEUM CENTER
  2-55. The theater petroleum center serves as the operational Army link to strategic petroleum partners,
  providing liaison between DLA Energy, host/partner nations, the ASCC, Army Petroleum Center, CCMD,
  and TSC as needed. It serves as the senior theater Army petroleum advisor to the CCMD through operational
  planning support to the TSC petroleum and water branch or ASCC petroleum and water branch staffs. The
  theater petroleum and water group operates as a sub-unit of the theater petroleum center and provides the
  same capabilities of the theater petroleum center on a smaller scale. Both the theater petroleum center and
  the theater petroleum and water group are normally attached to an ASCC, TSC, or ESC as mission dictates.
  See ATP 4-43 for additional information.
  TRANSPORTATION BRIGADE EXPEDITIONARY
  2-56. The transportation brigade expeditionary (TBX) is normally attached to a TSC or ESC. It provides
  command and control of Army watercraft and water terminal organizations for port opening and operations
  at inland waterway, bare beach, degraded, and improved sea terminals. Water terminal and watercraft units
  assigned to the TBX conduct deployment, distribution support, and redeployment in accordance with theater
  Army operational requirements. The TBX commander and staff serve as the TSC or ESC commander's
  primary experts on port operations. Watercraft assigned to the TBX can also be used to support the movement
  and sustainment of maneuver forces and their equipment when required. The TBX also serves as the ARFOR
  component of any JTF for joint logistics over-the-shore (JLOTS) operations. As the primary Army
  headquarters element with assigned terminal and watercraft units, the TBX provides the Army's organic
  capability to conduct specific functions of the Army in support of amphibious operations, riverine operations,
  wet-gap operations, JLOTS operations, and intratheater transport of time-sensitive, mission-critical personnel
  and materiel. See ATP 4-13 for additional information.
  EXPLOSIVE ORDNANCE DISPOSAL GROUP
  2-57. The EOD group conducts mission command, planning, and control for all EOD assets in a theater and
  provides EOD liaison to the theater Army. The EOD group can conduct EOD command and control for two
  to six EOD battalions. It is attached or placed OPCON to coordinate EOD and weapons technical intelligence
  operations to a theater Army, corps, or JTF in support of a specific operation, OPORD, OPLAN, or concept
  plan. The group may also form the core of a specialized combined JTF with mission command of various
  enablers. If augmented, the group can provide command and control functions to execute missions such as
  facilitating collection of technical intelligence or management of captured enemy ammunition. See JP 3-42,
  ATP 4-32, ATP 4-32.1, ATP 4-32.2, and ATP 4-32.3 for additional information.
