VMF (Variable Message Format) enables the real-time exchange of digital tactical information in surveillance systems, command and control (C2) systems, and striking systems in a limited resource-based network-centric operational environment (NCOE) using both wired and wireless military communications.
The variable message format is a military digital information exchange standard established by the Joint Interoperability of Tactical Command and Control Systems (JINTACCS) program under the United States Joint Chiefs of Staff.
VMF provides common interoperability standards, including command data elements and protocol standards for information transfer in command, control, communications, computer and intelligence (C4I) systems over limited battlefield networks.
One substantial benefit of Variable Message Format is that its information coding standard is bit-oriented. Messages are passed vie binary code. It cannot only reduce the amount of data transmitted, but also improve machine automatically recognize and deal with the message easily.
According to the DoD, VMF is ideally suited to the following:
- Fire support
- Close air support
- Situational awareness
- Logistics
Each VMF message is typically preceded by a message header which is defined in MIL-STD2045-47001.
The header is an essential part of the transmission because it contains addressing data, Receipt/Compliance information, classification, precedence, message number etc. In MIDS/Link 16, most of this data is found in the messages themselves.
