  three engineer disciplines. Upon deployment, it serves as the senior engineer headquarters for a land
  component headquarters or theater army, based on mission requirements. The TEC—
  * Maintains primary responsibility for theater infrastructure development.
  * Synchronizes engineer efforts for the ASCC. The ASCC commander provides contingency
  training support and support of military engagement for supported respective commands.
  * Deploys staff elements and organizations under ASCC authority.
  * Provides a wide range of technical engineering expertise and support.
  * Consists of a command section and a deputy command section and deploys their main command
  post (CP) and two deployable CPs.
  Engineer unit task organization is tailored to meet anticipated requirements based on mission analysis.
  The divisional engineer force is typically organized under a functional engineer brigade headquarters or
  multifunctional headquarters, such as a MEB. In some situations, the division may require a combination of
  engineer forces that are organized under both functional and multifunctional headquarters.
  Typically, an engineer brigade is aligned to a corps or division. The brigade can control up to five
  mission-tailored engineer battalions that are not organic to maneuver units. The battalions have capabilities
  from any of the three engineer disciplines. The engineer brigade may serve as a joint engineer headquarters
  and may be the senior engineer headquarters deployed in an AO if a full TEC deployment is not required.
  The engineer brigade headquarters—
  * Provides C2 for assigned, attached, or OPCON units of nonengineer units performing missions in
  support of a deliberate gap (river) crossing.
  * Plans, supervises, and coordinates for engineer support to combat operations, construction, facility
  rehabilitation, task organization, resource management, river crossings, barrier placements,
  countermines, and counterobstacles.
  * Provides one deployable CP with engineer staff expertise in technical planning, design, quality
  assurance and control, geospatial and terrain analysis, and the oversight of contract construction
  and labor.
  * Provides support at an SPOD or APOD (missions are terrain-focused) during early-entry
  operations or support to a movement corridor within a corps AO.
  * Assists with the generation, management, analysis, and dissemination of geospatial data for the
  TGD. The geospatial engineer team captures and includes field-collected data into the TGD for
  use by all units.
  The engineer battalion provides organic C2 for one headquarters and headquarters company and one
  forward support company. The engineer battalion is assigned any variation of up to five engineer companies.
  When appropriately task-organized, it can provide C2 for combat and general engineering capabilities in
  support of a BCT, engineer brigade, or another unit. The engineer battalion can simultaneously support forces
  at all theater echelons. Due to habitual training relationships, some battalion headquarters are more capable
  in combat engineering than in general engineering or vice versa. Some battalion headquarters have additional
  capabilities (airborne, air assault, survey, design). The battalion may be focused on a single mission (route
  clearance, security, construction, cache inspection, reduction). The engineer battalion may be organized to
  perform as a breach force command when the BCT is conducting a combined arms breach. During a gap-
  crossing (river-crossing) operation, the engineer battalion provides the option to be designated as the
  crossing-site command.
