Army Techniques Publication ATP 6-02.70 Techniques for Spectrum Management Operations October 2019, establishes Army doctrine for Army spectrum management operations. This publication provides doctrinal guidance to Army spectrum users and describes how spectrum managers support commanders through the warfighting functions, the military decision making process, and the common operational picture (COP). This ATP provides technical descriptions of the spectrum management tools; including capabilities and compatibilities This ATP discusses ways to use the various spectrum management tools while performing spectrum management operations in support of unified land operations. The principal audience for ATP 6-02.70 is Army commanders, leaders and staffs at all levels, members of the Army profession whose duties involve spectrum management operations. Commanders and staffs of Army headquarters serving as joint task force 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 may also use this publication. This publication applies to the Active Army, Army National Guard/Army National Guard of the United States, and United States Army Reserve unless otherwise stated. This publication contains four chapters and six appendixes- Chapter 1 provides an overview of spectrum management operations, states the objectives, and describes spectrum management operations core functions. Chapter 2 discusses spectrum management operations support and input to the military decision making process and briefly describes the common operational picture. Spectrum managers provide support at every step of the military decision making process. Chapter 3 links Army spectrum management operations to the warfighting functions, describes how spectrum management operations support, and enables commander's efforts as they exercise command and control. Appendix A describes the electromagnetic spectrum manager task list and each supporting sub-tasks. This appendix also contains flow charts that show the collaboration process between electromagnetic spectrum managers and the CEMA element. Appendix B provides basic electromagnetic physics and underlying principles of the electromagnetic spectrum. Appendix C provides spectrum management tools, to include their compatibilities and capabilities to meet spectrum management operations critical tasks. These network centric systems are in many cases linked and accessible through Non-classified Internet Protocol Router Network (NIPRNET) and SECRET Internet Protocol Router Network (SIPRNET). Appendix D introduces the 12-step spectrum management lifecycle. This process serves as a guide to follow in establishing a functional and efficient spectrum management program. The lifecycle encompasses the complete process of providing spectrum management operations support to the commander and is applicable to all spectrum managers regardless of duty location. The Army spectrum management lifecycle utilizes the joint task force lifecycle adapted for the Army spectrum manager. Appendix E provides the reader with an overview of the military time zone designators. This appendix describes time zones for civilian and military uses. The chart, included in this appendix, provides a valuable tool to reference time zones in all parts of the world. Appendix F describes spectrum information and products necessary at the corps and joint task force levels. Spectrum managers are located within three organizations in a joint task force: the joint frequency management office, the joint electromagnetic spectrum operations cell, and joint spectrum management element. These agencies have a wide variety of inputs, collaboration, and products. This chapter shows input and products from different joint agencies displayed in table format.
