  Airspace Messages, Requests, and Information Displays
  This appendix discusses airspace messages, requests, and information displays. First,
  it discusses the types of digital messages. The appendix then discusses airspace
  coordinating measure and system peculiarities. Then the appendix concludes with a
  discussion on information displays.
  DIGITAL MESSAGES
  D-1. Digital messages consist of airspace messages, requests, and information displays. Airspace users
  transmit digital messages using two distinct formats compatible with multiple control systems within the data
  link architecture. The two primary formats used are United States message text format and joint variable
  message format. Digital airspace control systems, such as machine-to-machine exchange, determine
  appropriate formats to use for their particular systems. For example, TAIS communicates point-to-point with
  theater battle management core system via USMTF. Airspace users utilize USMTF predominantly on the
  Army mission command system and joint command and control automation systems. Airspace users utilize
  joint variable message format messages on the tactical Internet and at the platform level to support Force
  XXI Battle Command Brigade and below.
  UNITED STATES MESSAGE TEXT FORMATTING
  D-2. The USMTF establishes standards, rules, and conventions governing message text formats. USMTF is
  a set of character-oriented message text formats that provide common voice and automation templates to
  exchange information between joint command and control systems and enables interoperability for all
  military operations. The joint user handbook-message text formats (JUH-MTF) and FM 6-99 provide
  additional information on USMTF.
  D-3. The USMTF voice-message templates provide the means for units to communicate effectively during
  degraded network operations. Communicating expeditiously and succinctly via voice will remain a
  requirement due to the potential degraded network operations.
  D-4. Common USMTF voice templates used by airspace elements include the following:
  * Airspace coordinating measure request [ACMREQ]-REPORT NUMBER: A030 {USMTF #
  F658} (also the USMTF message for Munition Flight Path – MFP).
  * Airspace control order [ACO]-REPORT NUMBER: A035 {USMTF # F756}.
  * Air defense command message [AIRDEFCOM]-REPORT NUMBER: A010 {USMTF # E710}.
  * Airlift request [AIRLIFTREQ]-REPORT NUMBER: A015 {USMTF # D630}.
  * Air Mission Request Status/Tasking [REQSTATASK]-REPORT NUMBER: A020
  {USMTF # A661}.
  * Battlefield Support Geometry Message (SPRTGEOM) - REPORT NUMBER: XXX {USMTF
  #S201) (supports PAH/TAH dissemination and coordination).
  * Artillery Target Intelligence - Intelligence & Electronic Warfare (IEW) Target Coordination
  Message [ATIIEWTC] - REPORT NUMBER: XXX {USMTF #S308) (supports fire mission
  notification for airspace deconfliction and coordination).
  Note: These messages and reports may also be a record and are identified by “(Record)” at the
  end of the description.
