Engineer Support to Intelligence, Surveillance, and Reconnaissance
3-34. Engineer assessments and surveys are typically conducted at the operational level and in support of
the general engineering function. (Assessments and surveys are discussed in greater detail in FM 3-34.170
as technical reconnaissance support.) The assessment or survey teams are generally not employed when
direct contact with the enemy is likely. Rather, engineer assessment or survey is typically conducted in a
relatively secure area and is focused on specific and detailed technical information required for a future
engineer (or at least heavily engineered) mission. When operating within an assigned maneuver AO (BCT,
MEB, division, corps, JTF) the assessment or survey team must fully coordinate their activity with the
maneuver unit. However, the engineer team mission may or may not be an integrated part of the maneuver
unit reconnaissance operation. While combat engineer units conduct an assessment in some situations,
general engineer units are more likely to provide the required assessment or survey team. Additional
specialized assistance may also be provided from assets not typically organized into tactical units (USACE,
OGA, contractors, HN).
SUSTAINMENT CONSIDERATIONS
3-35. An engineer unit providing an ERT capability is likely able to provide only a limited amount of
logistics support, especially after the ERT crosses the line of departure (LD). For this reason, it is essential
that the supported unit understands and embraces the ERT requirements. The engineer unit must coordinate
closely with the brigade, battalion, or TF for support that they cannot provide or that can be provided more
effectively by the maneuver units. Examples include casualty evacuation, vehicle recovery, and
maintenance support (vehicle, communications, and weapon repair). Security considerations may also
require assistance from the supported unit.
3-36. For engineer units augmenting the BCT, staff coordination must be made at the appropriate battalion
or brigade level so that the supporting unit requirements are included in sustainment planning. Sustainment
planning at the battalion level is the primary responsibility of the battalion S-4. The battalion S-4
coordinates support for the attachments and verifies who is to provide this sustainment and how support for
attachments is to be requested. In coordination with all company executive officers (XOs) and first
sergeants (1SGs), the process is integrated into operations planning with the concept of logistics support
synchronized with operations. The attached unit leader must coordinate with the battalion personnel staff
officer (S-1), provide the S-1 a copy of his unit battle roster, and provide the battalion S-4 the status of all
key elements of equipment. The unit SOP should be the basis for battalion level sustainment operations
with planning to determine specific requirements and contingency preparation. The battalion and company
orders should address any specific support matters that deviate from the SOP.
