Brigade and Battalion Intelligence and Electronic Warfare Operations — FM 34-80

Intelligence and electronic warfare (IEW) support is critical to the success of the divisional brigades and battalions conduct of close operations. Commanders at these tactical echelons require accurate intelligence to plan the battle and timely combat information to win it. Counterintelligence (CI) support to battlefield deception and operations security (OPSEC) ensures the critical element of surprise and helps sustain the effective combat power of tactical forces. Electronic warfare (EW) provides combat information and targeting data for both maneuver and fire support units, protects friendly command, control, and communications (C3) systems, and augments maneuver and fires to suppress, neutralize, and destroy enemy C3 facilities. FM 34-80 is intended primarily for use by the intelligence staff officer (S2) and his section at the maneuver battalion and brigade levels. It describes the IEW tasks for which the S2 has responsibility and how the S2 operations are integrated into the command and staff process at the battalion and brigade levels. This manual may also be used by commanders, other staff officers, and military intelligence personnel within the division to gain a better understanding of the IEW system and IEW tasks applicable to brigade and battalion operations. For a more thorough understanding of tactical IEW doctrine, the reader should review FMs 34-1 and 34-10. FMs 71-3 and 71-2J should be reviewed for general doctrinal guidance for maneuver operations at the brigade and task force levels.
