This United States Army publication, Field Manual FM 6-99 U.S. Army Report and Message Formats May 2021, provides a standardized, readily available reference for Army forces to extract common voice reports and message templates. This manual is a collection of reports used by units of all sizes and forms the basis of Army voice information exchange in a degraded network environment. FM 6-99 facilitates a common understanding of voice reporting and communicating throughout U.S. Army elements and is the keystone manual for voice report and message formats.

The principal audience for FM 6-99 is all members of the profession of arms. Commanders and staffs of Army headquarters serving as joint task force or multinational headquarters should also refer to applicable joint or multinational doctrine, such as North Atlantic Treaty Organization (NATO) or American, British, Canadian, Australian, New Zealand (ABCANZ) doctrine, related to the range of military operations and joint or multinational forces. Joint and multinational doctrine aids interoperability. Trainers and educators throughout the Army also will use this manual. Note that some reports in FM 6-99 may contain portions that unit standard operating procedures eliminate or modify.
