Army Techniques Publication ATP 6-02.53 Techniques for Tactical Radio Operations January 2016 replaces Field Manual (FM) 6-02.53, Tactical Radio Operations and expands on the foundation of tactical radios operations found in FM 6-02, Signal Support to Operations. ATP 6-02.53 incorporates numerous changes. The Integrated Tactical Networking Environment is a combination and evolution of all three concepts through the integration of the software based networking radio technologies, and mission command mounted and mobile applications management. Communications and mobility are key enablers of mission command in support of the execution of successful unified land operations. Communications must support the Army's aim to seize, retain, and exploit the initiative to gain and maintain a position of relative advantage over the enemy in sustained land operations. Army forces must be able to move repeatedly and communicate. Tactical situations change rapidly during sustained land operations, requiring tactical radios that are versatile and readily adaptable to rapidly changing tactical situations. Communications in support of unified land operations require the employment of communications capabilities at squad level and higher echelons. Communications at the squad level enables communication and situational awareness at the lowest level possible. ATP 6-02.53 contains 12 chapters and 9 appendices- Ch 1 provides an overview of tactical radios, tactical radio networks, capabilities, and network management. Ch 2 addresses the employment of tactical radios at all echelons throughout the Army. Ch 3 addresses the tactical radio platforms and associated waveforms that Army forces employ at all echelons across all phases of operations. Ch 4 discusses the waveform and waveform application functional component of the tactical networking environment. Ch 5 describes the commercial-off-the-shelf very high frequency radios used to support tactical radio operations. Ch 6 addresses the ultrahigh frequency radios and systems that play a major role in network centric warfare. Ch 7 addresses the Army single channel tactical satellite capabilities associated with the legacy and enduring radio platform and planning considerations. Ch 8 addresses the airborne radios employed to provide communications for ground-to-air operations as well as air-to-air and air-to-sea missions. Ch 9 addresses various other tactical radio systems employed to enable communication and situational awareness during the conduct of operations. Ch 10 addresses antenna techniques, concepts, terms, types, effects, and provides examples of antenna field repairs. Ch 11 addresses key management techniques relative to protecting voice, data, and video information over tactical radio networks. Ch 12 addresses electronic warfare and the electronic protection techniques used to prevent enemy jamming and intrusion into friendly communications systems. App A provides a description of frequency modulation networks. App B identifies radio sets basic components, characteristics, properties of radio waves, wave modulation, and site considerations for single channel radios. App C addresses the importance of high frequency, very high frequency, ultrahigh frequency antenna selection. App D addresses radio operations in unusual environments. App E addresses the Julian date, synchronization time, and Zulu time. It also provides a time zone conversion chart. App F provides procedures for preventing a network compromise and addresses recovery options available to the commander and his staff. App G addresses data communications elements such as binary data, baud rate, modems, and forward error correction. App H addresses single channel ground airborne radio system implications and cosite interference mitigation. App I addresses the proper way to send messages over a radio as well as the proper procedures for opening and closing a radio net.
