Appendix B
Selected Engineer Organizations and Capabilities
This appendix describes organic engineer staffing and organizations within the BCT
and ACR. It also highlights some of the modular engineer units that are likely to
augment the BCT and ACR or provide support within their AO. (See FM 3-34 for a
more complete listing of engineer organizations.)
ORGANIC ENGINEERS IN THE BRIGADE COMBAT TEAM
B-1. Each BCT and ACR has an organic engineer company. In the HBCT and IBCT, the organic
engineer (Sapper) company is located within the BSTB. In the SBCT, it is positioned as a separate unit
under the brigade (see figure B-1, page B-5). The ACR combat engineer company is also positioned as a
separate unit under the regiment, similar to that of the SBCT. The engineer company organic to the BCT
and ACR is focused on tactical-level maneuver. Its mission is to provide assured mobility to the BCT and
ACR by conducting combat engineering (M/CM/S) and limited general engineering to enhance maneuver
in the AO. As a combat multiplier, engineers concentrate their efforts on maintaining the freedom of
movement for the supported force and reducing the enemy’s ability to mass and maneuver on the
battlefield.
B-2. There is an organic engineer staff element within each BCT and ACR (see figure B-2, page B-6).
Though each type of BCT is slightly different, there is generally an ENCOORD, engineer planner, senior
engineer NCO, and geospatial engineering team in the HBCT and IBCT. In addition there are also organic
engineer personnel within the BSTB, and within the HHC, CAB, and infantry battalion. Engineer
personnel within the BSTB facilitate additional engineer forces being attached to augment the HBCT or
IBCT. Engineer units from company size and below are intended to be attached to the BSTB for C2 and
logistics support.
B-3. The organic geospatial engineering team within the BCT operates in the BCT main CP and provides
geospatial engineering support. The topographic section—
� Generates and analyzes terrain data.
� Prepares decision graphics.
� Produces image maps.
� Provides 3-D terrain perspective views.
� Manages the theater geospatial database.
� Updates maps.
� Produces tactical decision aids.
� Produces IPB overlays.
� Operates on a 24-hour basis.
B-4. Equipment assigned to the topographic section includes—
� One Digital Topographic Support System (DTSS–B)–Base: AN/TYQ-67 (light).
� One DTSS–B: AN/TYQ-71 (deployable).
� One light medium tactical vehicle (LMTV) with towed generator.
� One high-mobility, multipurpose, wheeled vehicle (HMMWV).
B-5. Figures B-3 through B-6, page B-7 through B-10, show the organic engineer company in the ACR,
HBCT, IBCT, and SBCT.
