FM 3-38, Cyber Electromagnetic Activities, provides overarching doctrinal guidance and direction for conducting cyber electromagnetic activities (CEMA). This manual describes the importance of cyberspace and the electromagnetic spectrum (EMS) to Army forces and provides the tactics and procedures commanders and staffs use in planning, integrating, and synchronizing CEMA.
This manual provides the information necessary for Army forces to conduct CEMA that enable them to shape their operational environment and conduct unified land operations. It provides enough guidance for commanders and their staffs to develop innovative approaches to seize, retain, and exploit advantages throughout an operational environment. CEMA enable the Army to achieve desired effects in support of the commander’s objectives and intent.
The principal audience for FM 3-38 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as joint task force or multinational headquarters should see applicable joint or multinational doctrine concerning cyberspace operations, electronic warfare (EW), and spectrum management operations (SMO).

Commanders at all levels ensure their Soldiers operate in accordance with the law of war and the rules of engagement (see FM 27-10).
