MIL-STD-2525B (w/ CHANGE 2), DEPARTMENT OF DEFENSE INTERFACE STANDARD: COMMON WARFIGHTING SYMBOLOGY (7 MAR 2007)., 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 hand-drawn 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.【英文标准名称】:Informationtechnology-3,81mmwidemagnetictapecartridgeforinformationinterchange-Helicalscanrecording-DDS-DCformatusing60mand90mlengthtapes
