Engineer Support to the Brigade Combat Team
command. For conducting construction or EH clearance missions, the battalion receives construction
design, survey, or EH teams to facilitate these missions.
BASELINE ENGINEERING UNITS
1-15. Baseline engineering units include combat and general engineering units (see table 1-1). They are the
primary building blocks for the organization of most engineer battalions. These units are used to augment
the organic engineer capabilities of a BCT and may be task-organized under an engineer battalion
headquarters to serve under a variety of larger headquarters, providing the specific tailored capabilities
needed to support any particular mission requirements. (See appendix B for more detailed information on
baseline engineering units.)

Combat Engineering Units
1-16. Baseline combat engineering units are focused on supporting combined arms operations at the
tactical level and are designed to participate in close combat operations as necessary. All 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 units when
two or more are assigned to a BCT. Sapper units may construct tactical obstacles, defensive positions, and
fixed and float bridges; repair command posts (CPs), lines of communication (LOCs), tactical routes,
culverts, and fords; and conduct other selected general (horizontal and vertical, construction-related)
engineering tasks. Combat engineering units also provide engineer support for gap- and river-crossing
operations, assist in assaulting fortified positions, and conduct breaching operations. Airborne- and air
assault-capable engineer units also have the unique ability to employ air-droppable, rapid runway repair
kits in support of forcible-entry operations. The more specialized combat engineering capabilities of assault
bridging, breaching, and route and area clearance are added to the organic engineer capabilities in BCTs or
to deployed baseline Sapper companies to allow them to accomplish their broader mission requirements.
General Engineering Units
1-17. General engineering units are comprised of bridging, support, and construction capabilities. The
horizontal and vertical companies have a construction focus and are capable of constructing, rehabilitating,
repairing, maintaining, and modifying landing strips, airfields, CPs, main supply routes (MSRs), supply
locations, building structures, bridges, and other related aspects of the infrastructure. These units may also
perform repairs and limited reconstruction of railroads or water and sewage facilities. The basic capabilities
of these construction units can be significantly expanded. Through the augmentation of specialized
personnel and equipment, these baseline construction units can provide bituminous mixing and paving,
quarry and crushing operations, and major horizontal construction projects (highways, storage facilities,
airfields). Additional augmentation could also include pipeline construction or dive support depending on
the type and scope of the construction mission.
SPECIALIZED ENGINEERING UNITS
1-18. Specialized engineering units are a variety of typically low-density engineer forces that provide the
remaining category of engineer support. They are technically focused units that provide selected support at
the tactical level. These specialized forces include modules for construction support, infrastructure
development, EH mitigation, mine detection dogs, geospatial support, well drilling, real estate
management, and firefighting.
