  Brigade Combat Team Geospatial Engineering Staff
  Two types of geospatial engineer elements exist in brigade and BCT staffs. The two types of geospatial
  teams are the geospatial engineer team and the geospatial intelligence team. Geospatial engineering teams
  support functional and multifunctional brigades (aviation, engineer, sustainment, division artillery,
  expeditionary military intelligence, fires, maneuver enhancement and security force assistance). Geospatial
  intelligence teams support BCTs, divisions, and corps and are typically assigned to the assistant chief of staff,
  intelligence (G-2), but they can also be task-organized into other staff sections. Geospatial engineers within
  a geospatial engineering team or geospatial intelligence cell provide geospatial support to the assigned
  echelon and lower.
  SECURITY FORCE ASSISTANCE BRIGADE—BRIGADE ENGINEER BATTALION
  The BEB under the Security Force Assistance Brigade is designed to provide C2 to the Security Force
  Assistance Brigade BCT and to provide engineer technical and tactical advisory support to HNs. The mission
  of the Security Force Assistance Brigade BEB is to provide C2 of attached and assigned units in support of
  the Security Force Assistance Brigade’s and CCDR’s objectives to train, advise, and assist foreign security
  forces by teaching, coaching, mentoring, and providing direct access to coalition capabilities. The sizes and
  numbers of advising teams may adjust based on the assigned mission. The headquarters at company and
  battalion support dispersed teams across the AO.
  ECHELONS ABOVE BRIGADE
  Engineer headquarters C2 subordinate elements. Each EAB headquarters has a staff that assists the
  commander to C2 engineer organizations and other task-organized units, supporting multifunctional missions
  (combined arms breaching, combined arms gap crossing). The units in this category consist of the TEC,
  engineer brigade, and engineer battalion.
  Baseline engineer units provide combat and general engineering capabilities that are primarily focused
  on enabling tactical operations. Baseline engineer units are used to augment BCT engineers and to provide
  engineering capabilities to EAB engineer headquarters. When supporting a division or a corps, baseline
  engineer units are typically attached to, or are under the OPCON of, an engineer brigade or a maneuver
  enhancement brigade (MEB). When supporting echelons above corps, the baseline engineer units are
  normally attached to, or are under the OPCON of, a functional engineer brigade, TEC, or MEB.
  Specialized engineer units are technically oriented (often low-density) units that provide specialized
  capabilities in construction support, infrastructure development, explosive hazards mitigation, geospatial
  support, well drilling, military working dog units, prime power, diving, and firefighting. The specialized
  engineer units primarily support the operational to strategic levels, but they also provide selected support at
  the tactical level.
  Engineer Headquarters
  There are three echelons of engineer headquarters units—the TEC, engineer brigade, and engineer
  battalion. Multifunctional units may also provide C2 for engineer forces when engineer support is integral to
  the multifunctional mission. The engineer battalion is most often found in the engineer brigade, in a MEB,
  or in support of a BCT. The engineer brigade, one of the Army functional brigades, provides C2 for up to
  five engineer battalions at the division and corps levels. While not an engineer headquarters unit, the MEB
  is a significant headquarters for the employment of engineering capabilities. See FM 3-81 for additional
  information on the MEB.
  The theater army normally receives one TEC. The TEC is designed to have C2 of assigned or attached
  engineer brigades, other engineer units, and contracted construction engineers within the supported theater
  army area of responsibility (AOR). When directed, the TEC serves as the core for the creation of a joint
  forces engineer component command. The TEC focuses on operational-level engineer support across the
