Description: This publication defines and standardizes multi-Service brevity codes agreed upon by each U.S. Service branch. A brevity code provides no additional communications security. Brevity codes only serve to shorten transmissions. This publication does not include service-specific brevity codes nor is it synonymous with NATO APP-7. Updates to this publication have been shared with the NATO Standardization Office for inclusion or modification into Allied Communications Publications.
