(formally titled "NATO Standard APP-11: NATO Joint Military Symbology" ) is the official standardization agreement (STANAG) that defines the symbols used on all NATO military maps, displays, and digital systems.

While summaries and guidelines are often available on platforms like Scribd or through industry partners like Accuris , official ratified versions for military use must be obtained through the NATO Standardization Office (NSO).
