In the preface, it states:
"Field Manual 34-1 is the Army's capstone manual for military intelligence (MI) doctrine. It is consistent with and expands doctrine contained in FM 100-5, the Army's operations doctrine. It describes the Intelligence Battlefield Operating System (BOS) and electronic warfare (EW) and how they support operations. It provides the guidance needed by MI personnel to support the commander with intelligence and electronic warfare (IEW) in warfighting and in operations other than war (OOTW). When thinking about IEW support in the context of this manual, one should remember that America's Army and its Intelligence Corps is a doctrinally based institution. Doctrine is neither unchanging dogma nor the exclusive purview of an intellectual elite. Neither is it merely rigid adherence to a set of tactics, techniques, and procedures (TTP) that tell us "how to fight." Doctrine provides a common, flexible framework of thought and expectations within which soldiers think about and debate the issues of our profession. Doctrine provides a basis for the institution to incorporate new ideas, technologies, and organizational design to help leaders become the adaptive, creative problem solvers that modern military operations require. Direct combat, humanitarian relief, or disaster recovery-all have in common, methods for organizing and carrying out assigned IEW missions. To change our doctrine is, therefore, to change the way in which we think and debate the intellectual and physical means for ensuring our continuity of purpose. This manual serves as a basis for IEW doctrine, training, and combat developments, and is the foundation for Army service school IEW instruction. It addresses the Intelligence BOS and MI unit functions in a force projection army, across the full scope of military operations through all phases of crisis response. It describes the seamless nature of the Intelligence BOS, its structure, and how its organizations operate. It also describes the Army MI."
This manual is produced by the U.S. Army Intelligence Center and Fort Huachuca (Arizona). It is fully illustrated with numerous line drawings.
