MIL-STD-2525B (w/ CHANGE 1), DEPARTMENT OF DEFENSE INTERFACE STANDARD: COMMON WARFIGHTING SYMBOLOGY (01 JUL 2005)., This standard provides common warfighting symbology along with details on its display and plotting to ensure the compatibility, and to the greatest extent possible, the interoperability of DOD Command, Control, Communications, Computer, and Intelligence (C4I) systems development, operations, and training. The standard addresses the efficient transmission of symbology information within the infosphere through the use of a standard methodology for symbol hierarchy and symbol identifiers.
