Other information APP-6 organization chart of the 1st Marine Expeditionary Force (MEF): A quick reference chart for friendly icons: MIL-STD-2525A APP-6A, Military Symbols for Land Based Systems was developed directly from MIL-STD-2525A, Common Warfighting Symbology. MIL-STD 2525A was the American standard for military symbols. The custodian of APP-6 is the United States. APP-6(A) remained unchanged as work on harmonizing it with ADatP-3, NATO Message Text Formatting System was carried out. In 1999, APP-6 was moved from the Army Service Board to the Joint Service Board. With this move, APP-6 was placed under the Information Exchange Requirements Harmonization/Message Text Format Working Group. The IERH/MTFWG then formed the Joint Symbology Panel to provide configuration management of APP-6 with the US custodian as the chairman. With the ratification and promulgation of APP-6(B) in 2008, the named was changed to NATO Military Symbology to better reflect the nature of the publication. In 2011, with the introduction of APP-6(C), the named was changed to NATO Joint Military Symbology. The US military required new symbols to support ongoing operations in Iraq and Afghanistan, so the pace of change between APP-6 and MIL-STD-2525 remained uneven until 2009. In 2009, a new chairman for DOD Symbology Standardization Management Committee was appointed, and the two configuration management organizations began to work together. The two organizations held joint meetings with full participation on both sides. The goal of both groups is to develop comprehensive joint military symbology that is common to both organizations to the greatest extent possible. APP-6(C) began the process of changing the format of the publications and introduced new symbol identification codes. MIL-STD-2525D has carried that one step further with more symbols and more symbol sets derived from recent NATO and US operations. MIL-STD-2525D
