Field Manual FM 3-12 (FM 3-38) Cyberspace and Electronic Warfare Operations April 2017 Over the past decade of conflict, the U.S. Army has deployed the most capable communications systems in its history. U.S. forces dominated cyberspace and the electromagnetic spectrum (EMS) in Afghanistan and Iraq against enemies and adversaries lacking the technical capabilities to challenge our superiority in cyberspace. However, regional peers have since demonstrated impressive capabilities in a hybrid operational environment that threaten the Army's dominance in cyberspace and the EMS. The Department of Defense information network-Army (DODIN-A) is an essential warfighting platform foundational to the success of all unified land operations. Effectively operating, securing, and defending this network and associated data is essential to the success of commanders at all echelons. We must anticipate that future enemies and adversaries will persistently attempt to infiltrate, exploit, and degrade access to our networks...

Field Manual FM 3-12 (FM 3-38) Cyberspace and Electronic Warfare Operations April 2017 Over the past decade of conflict, the U.S. Army has deployed the most capable communications systems in its history. U.S. forces dominated cyberspace and the electromagnetic spectrum (EMS) in Afghanistan and Iraq against enemies and adversaries lacking the technical capabilities to challenge our superiority in cyberspace. However, regional peers have since demonstrated impressive capabilities in a hybrid operational environment that threaten the Army's dominance in cyberspace and the EMS. The Department of Defense information network-Army (DODIN-A) is an essential warfighting platform foundational to the success of all unified land operations. Effectively operating, securing, and defending this network and associated data is essential to the success of commanders at all echelons. We must anticipate that future enemies and adversaries will persistently attempt to infiltrate, exploit, and degrade access to our networks and data. A commander who loses the ability to access mission command systems, or whose operational data is compromised, risks the loss of lives and critical resources, or mission failure. In the future, as adversary and enemy capabilities grow, our ability to dominate cyberspace and the EMS will become more complex and critical to mission success. Incorporating cyberspace electromagnetic activities (CEMA) throughout all phases of an operation is key to obtaining and maintaining freedom of maneuver in cyberspace and the EMS while denying the same to enemies and adversaries. CEMA synchronizes capabilities across domains and warfighting functions and maximizes complementary effects in and through cyberspace and the EMS. Intelligence, signal, information operations (IO), cyberspace, space, and fires operations are critical to planning, synchronizing, and executing cyberspace and electronic warfare (EW) operations. CEMA optimizes cyberspace and EW effects when integrated throughout Army operations. FM 3-12 defines and describes the tactics to address future challenges while providing an overview of cyberspace and EW operations, planning, integration, and synchronization through CEMA. It describes how CEMA supports operations and the accomplishment of commander's objectives, and identifies the units that conduct these operations. Due to the rapidly revolving cyberspace domain, the Cyber COE will review and update FM 3-12 and supporting publications on a frequent basis in order to keep pace with a continuously evolving cyberspace domain.

FM 3-12 provides tactics and procedures for the coordination and integration of Army cyberspace and electronic warfare operations to support unified land operations and joint operations. FM 3-12 explains Army cyberspace and electronic warfare operations fundamentals, terms, and definitions. This publication provides overarching guidance to commanders and staffs on Army cyberspace and electronic warfare operations at all echelons.

The Army and joint force must adapt and prepare for large-scale combat operations in highly contested, lethality to exploit. The reduction of friendly, forward-stationedforces, significant reductions in capability and capacity across the entire joint force, and the pace of modernizationmake it imperative that we do everything possible to prepare for worst-case scenarios. We must be ready to winwith the forces we have, and having the right doctrine is a critical part

This field manual aims to provide techniques to assist planners in planning, coordinating, executing, synchronizing, and assessing military deception (MILDEC). While the means and techniques may evolve over generations, the principles and fundamentals of deception planning remain constant. FM 3-13.4 applies to all members of the Army profession: leaders, Soldiers, Army Civilians, and contractors. The principal audience for this publication is Army commanders, staffs, and all leaders. Commanders and staffs of Army headquarters serving as joint task force or multinational headquarters should refer to applicable joint or multinational doctrine concerning joint or multinational planning. Trainers and educators throughout the Army also use this publication as a guide for teaching MILDEC. Commanders, staffs, and subordinates ensure their decisions and actions comply with applicable U.S., international, and, in some cases, host-nation laws and regulations.

ADP 3-0, Operations, constitutes the Army's view of how to conduct prompt and sustained operations across multiple domains, and it sets the foundation for developing other principles, tactics, techniques, and procedures detailed in subordinate doctrine publications. It articulates the Army's operational doctrine for unified land operations. ADP 3-0 accounts for the uncertainty of operations and recognizes that a military operation is a human undertaking. Additionally, this publication is the foundation for training and Army education system curricula related to unified land operations. The principal audience for ADP 3-0 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as joint task force (JTF) or multinational headquarters should also refer to applicable joint or multinational doctrine concerning the range of military operations and joint or multinational forces. Trainers and educators throughout the Army will use this publication as well.

"Early-career officers in tactical units must understand and operate in an increasingly complex information environment. Poor communication with command-level decisionmakers and errors in judgment can be costly in the face of sophisticated adversary capabilities and while operating among civilian populations. There are few opportunities for formal education and training to help officers prepare for operations in the information environment (OIE), and it can be difficult to know how to employ the tactics, techniques, and procedures of tactical-level maneuver-focused operations in support of OIE-related capabilities and activities. With its quick-reference format and series of illustrative vignettes, this handbook is intended to facilitate tactical problem-solving and increase officers' awareness of when and how they can contribute to the goals of OIE."--Back cover.
