scope:

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. The standard applies to both automated and handdrawn graphic displays. These symbols are designed to enhance DOD's joint warfighting interoperability by providing a standard set of common C4I symbols. Additional symbol sets may be provided when this document is updated.

Purpose.

This standard is designed to provide the guidelines and criteria necessary for the development and display of standard C4I warrior symbology. The requirement to standardize C4I warfighting symbology in order to provide a family of symbology standards in support of the C4I For The Warrior (C4IFTW) concept was recognized at the 30 August 1993 meeting of the Military Communications-Electronics Board. To satisfy these needs, common warfighting symbology standardization incorporates MIL-STD-2525B, Common Warfighting Symbology, a DOD symbol data repository, and supporting documentation such as the Symbology Information Technology Standards Management Plan, Configuration Management Plan, and Symbology Standards Management Committee (SSMC) charter (see figure 1).

Applicability.

This standard applies to all DOD components directly or indirectly involved with C4I operations, system operations, system development, and training within the context of warfighting operations. MIL-STD-2525B will serve as the standard symbol set for all future DOD uses of C4I symbology. The standard can be applied to mapping/charting, weather, cockpit display, and engineering design symbology to the extent that it is usable by these communities. The standard will apply to all future use of symbols in two-dimensional and electronic display systems in C4I environments.

MIL-STD-2525B combines the symbology from two separate usage domains, referred to as the "force domain" and the "engagement domain." These domains use warfighting symbology in support of their C4IFTW functions. When integrated, this symbology provides the basis for a final standard solution for C4IFTW symbology.

Symbology used in the force domain has evolved from North Atlantic Treaty Organization (NATO) Standardization Agreement (STANAG) 2019 (APP 6), Military Symbols for Land Based Systems, and U.S. Army Field Manual (FM) 1-02/Marine Corps Reference Publication (MCRP) 5-12A, Operational Terms and Graphics. Commanders and staff at all echelons use the symbols and graphics contained in these documents for planning and execution of ground force military operations. These symbols represent units, installations, equipment, and operations, and are used in automated C4I systems or to mark maps and overlays manually.

Symbology used in the engagement domain has evolved from the requirement to plot sea and air tracks on cockpit, radar, weapons control, and command and control tactical displays. Joint Tactical Information Distribution System (JTIDS) and Naval Tactical Data System (NTDS) symbology, and most recently, "Display Symbology and Colors for NATO Maritime Units," have been the primary sources for track symbols used within the engagement domain.

MIL-STD-1787-Aircraft Display Symbology has been developed to provide standards guidance regarding rotary and fixed wing cockpit displays. MIL-STD-1787 supersedes MILSTD- 1295A.
