  Baseline Engineer Units
  Baseline engineer units include combat and general engineer units. The baseline engineer units are the
  primary building blocks for the organization of most engineer battalions. These units may augment the
  organic engineering capabilities of a BCT, or they may be task-organized under an engineer battalion
  headquarters to provide specific tailored capabilities to the EAB.
  Baseline combat engineer units are focused on supporting combined arms operations at the tactical
  level. The baseline combat engineer units are designed to provide support to maneuver forces. Engineers
  have the capability to fight as engineers or, if required, as infantry. An engineer battalion headquarters is
  typically included to provide the necessary C2, logistics, and staff supervision for attached and assigned
  combat engineer units when two or more are assigned to a BCT, a MEB, or another organization. Combat
  engineer units may construct tactical obstacles, defensive positions, and fixed and float bridges; repair CPs,
  tactical routes, culverts, and fords; and conduct general engineering tasks related to horizontal and vertical
  construction when augmented with the appropriate tools, equipment, and training. Combat engineer units
  also provide engineer support for gap-crossing operations, assist in assaulting fortified positions, and conduct
  breaching operations. Airborne and air assault-capable engineer units have the unique ability to employ air-
  droppable, rapid runway repair kits to support forcible, early-entry operations. The more specialized combat
  engineering capabilities of assault bridging, breaching, and route and area clearance are added to the organic
  engineering capabilities in BCTs (or to deployed baseline Sapper companies) when required by the mission.
  Baseline general engineer units include horizontal and vertical construction, engineer support,
  bridging, mobility augmentation, and clearance companies. The baseline general engineer units construct,
  rehabilitate, repair, maintain, and modify CPs, LOCs, supply installations, building structures, bridges, and
  other related aspects of the infrastructure. These units may also perform repairs and limited reconstruction of
  railroads and water and waste facilities. The basic capabilities of these units can be expanded by augmenting
  them with additional personnel, equipment, and training from specialized engineer units or other sources.
  Such augmentation gives them the capability to conduct quarrying and crushing, pipeline support, horizontal
  and vertical construction support, dive support, and major horizontal construction projects (highways, storage
  facilities, airfields).
  Specialized Engineer Units
  Specialized engineer units provide explosive hazards support and general and geospatial engineering
  capabilities at the operational and strategic levels, and they often augment those capabilities down to the
  tactical level. Many capabilities are lower density than those of the baseline engineer units. These smaller,
  more specialized units are designed to support technical aspects within larger, engineer-related missions or
  to augment headquarters elements with unique technical engineering skills.
  Construction support includes the following capabilities:
  * Asphalt teams.
  * Concrete sections.
  * Construction management teams.
  * An engineer facility detachment.
  * An engineer utilities detachment.
  * A forward engineer support team–advanced (FEST-A).
  * A forward engineer support team–main (FEST-M).
  * Quarry platoons.
  * Well-drilling teams.
