Engineer Support to Intelligence, Surveillance, and Reconnaissance
� Reconnaissance in force.
� Route reconnaissance.
� Reconnaissance patrol.
3-12. Most tactical engineer reconnaissance capabilities enable the collection of technical information in
support of the combat engineer function. Reconnaissance in support of M/CM/S operations is conducted
primarily by ERTs comprised of combat engineers and has a focus on the collection of tactical and
technical information to support BCT freedom of maneuver and protection of friendly forces and facilities.
FM 3-34.170 provides a detailed discussion of reconnaissance support of the five functional areas of
mobility operations, obstacle integration and turnover in countermobility operations, fighting and other
protective positions, and other tactical operations in the BCT. The specific combat engineer reconnaissance
tasks include, but are not limited to—
� Obstacle reconnaissance focused on bypass or breach of obstacles to create OBSTINTEL.
� Route reconnaissance focused on route clearance operations.
� Area reconnaissance focused on EHs, such as mines and UXO, requiring area clearance
operations.
� Crossing-site reconnaissance focused on determining requirements for a gap crossing.
� Route reconnaissance focused on establishing a combat road or trail.
� Reconnaissance of planned or existing sites and facilities supporting forward aviation
operations.
� Obstacle reconnaissance (to include demolition obstacles) focused on establishing friendly
obstacles integrated with fires.
� Obstacle reconnaissance in preparation for target turnover.
� Area reconnaissance focused on establishing vehicle fighting positions or protective works.
� Area reconnaissance in support of urban combat operations.
� Reconnaissance of tunnels and underground structures.
� Reconnaissance to establish an initial assessment of environmental factors.
� Reconnaissance to establish an initial assessment of infrastructure factors.
� Reconnaissance in complex terrain.
� Reconnaissance in conjunction with other engineer missions (route clearance, construction, and
so forth).
3-13. General engineers augmenting the BCT can provide a range of technical reconnaissance capabilities
that enable missions linked to BCT sustainment. General engineers may be teamed with ERTs, other BCT
units, or in stand-alone organizations. These tasks are tactical missions that include the requirement to
gather technical information needed for—
� MSR maintenance and upgrade.
� General engineering in support of airfields and heliports.
� Bridge construction or repair.
� General engineering in support of protection.
� Procurement and production of construction materials.
� General engineering in support of real estate support.
ENGINEER COORDINATOR
3-14. The ENCOORD is responsible for the application, coordination, and integration of engineer
reconnaissance. In this role, the ENCOORD is a critical link in the commander’s IM processes that provide
the translation from the gaps identified by the commander in CCIR to the technical information focus of
engineer reconnaissance. ENCOORD participation in the ISR working group facilitates a concerted effort
in planning and integrating engineer reconnaissance. The ISR meeting is a critical event in the BCT battle
rhythm. The ENCOORD or his representative must be prepared for each meeting to discuss the availability
of engineer reconnaissance assets, capabilities, limitations, and IR related to engineer operations.
