This army field manual describes how engineer recon teams support and augment a maneuver battalion or brigade's recon effort.

This manual serves as a guide for both brigade and task force (TF) engineers, as well as for subordinate leaders (especially recon team leaders) in planning, integrating, and conducting recon operations.

It also serves as a guide for the brigade and TF staffs and subordinate maneuver commanders on the organization, capabilities, and employment of engineer recon teams.

This manual sets forth the principles of conducting engineer recon activities supporting a maneuver brigade or TF. It addresses engineer tactics, techniques, and procedures (TTP) that highlight critical principles.

However, the TTP are intended to be descriptive rather than prescriptive; they are not a replacement for the TTP and standing operating procedures (SOPs) that are unique to the supported unit.
