NATO Joint Military Symbology is the NATO standard for military map marking symbols. Originally published in 1986 as Allied Procedural Publication 6 (APP-6), NATO Military Symbols for Land Based Systems the standard has evolved over the years and is currently in its fourth version (APP-6C). The symbols are designed to enhance NATO’s joint interoperability by providing a standard set of common symbols. APP-6 constituted a single system of joint military symbology for land, air, space and sea based formations and units, which can be displayed for either automated map display systems or for manual map marking. It covers all of the joint services and can be used by them.
